Ah damn, I never posted that bit about the projection.
Well, basically you are slightly screwed. About 0.2 bumparelles, which isn't life-threatening. The map is what cartographers call in the "oh god what are these people doing here" projection. The simplest way to fix this is to stretch either the horizontal or vertical, or both axises so that their ratios are two to on, and then fix the poles. Here, you'd have to either fix the north pole by either creating a northern coast on the northern continent, or streth the northern bits of the northern continent so that covers the whole upper edge of the map. Let me show you what happens with your current map:
...
Huh, it doesn't actually look that bad.
It's kinda.... Alright.
well. You could probably just adjust the map so that it's 2x1, and then it's propah equirectangular.
Hmm, yeah, actually it doesn't look too bad. It just takes recognizing the fact that the land around the pole area is really a lot more compact, that is, if you plan to put anything there. It's a bit of an extreme environment, so I wouldn't expect a lot of human habitations in that region anyway.
I think, therefore I am a nerd.
Cogito, ergo sum nerdem.

Pimping my worldmap here. Still WIP... long way to go, but I'm pretty proud of what I've done so far...
Yeah, after Karro mentioned something about it when I first uploaded the pictures, I plugged it into GIMP, mapped to a sphere, and rotated it to check. I'm not happy with the pointedness, but basically I think what I'm going to do for the easy fix for now, is possibly to soften up those mountains at the pole, and try to round out the island a little. I might make a little line of land all the way across the top to pull it off. I've got some playing with it to do.
As for Equirectangular, exactly which parts are 2:1? I don't think I quite follow, yet.

On an equirectangular map, the whole map is 2:1 in size. Each pixel represents an X degree by Y degree area, so it's easily computable, but there's a lot of distortion. On an equirectangular map, you can make a graticule by simply creating a gridline that is twice as many squares wide as it is high, see attachments: the first is a stretched version of your map into equirectangular, the second is a sinusoidal projection, and a third is a vertical perspective "as seen from space" projection to show the difference.

Well, I haven't fixed the projection, yet, but I did map out the rough precipitation for January and July. Some of it is a little iffy, but I figure I can fix most of the glaring issues when I do the climates/biomes.
Average precipitation over continents with temperature overlay over oceans:
January:
July:

EDIT: I kept working in patches today in between researching and a few other things, and blocked out some rough climatological regions. I think I have quite a few mistakes in here, as well, but I have a feeling I probably won't have much time to fix them until next weekend, so I'm posting what I have so far for feedback.
The text overlay lists a rough Köppen Climate classification ID.

Well, I finally decided I'd waited long enough to rough up my coasts a little bit. So, going back and finding RobA's "Not So Random Coastlines" tutorial, and adapting it to Photoshop as best as possible (to be honest, I was too lazy to pull up Gimp, heh), I tried to rough up my coasts a little and make them look a little more realistic.
'New' Continent forms:
For comparison, here is the same image with the old outline visible:
And for fun and an idea, here are the new continents coloured green, with the rough mountain guides visible:
The southern continent needs much more work, still, but I'm reasonably happy with the middle continent and the northern continent is passable due to the large amounts of ice for much of the year (that's my excuse, and I'm stickin' to it!). I might do some more work on the Southern Continent tonight, but it's not very likely. Hopefully I'll have more in a few days, though, as I steal some time for it. I haven't decided how much I'm changing the northern continent beyond this, yet. Time will tell.

I love RobA's not so random coastline tutorial. Looking to see how you are going to develop the mountain spines!
Looking really good
Keep going please despite the brain pain i know it must be causing (mine has currently melted )

So do I! I'd thought about something roughly similar before seeing his, but hadn't the foggiest how to pull it off, until I saw his tutorial. The only thing I didn't like was the lack of detail I was getting with my continents, without losing things like the strait between the two northern continents, and all my island chains. So what I ended up doing was running the process with a relatively low gaussian blur (as I was using Photoshop), to rough them up just slightly. And then in the locations where I wanted/needed a little more variety, I ran a rough lasso selection around them, feathered it so as to blend, and rendered Photoshop's Difference Clouds on top of the clouds (I forget the Gimp analog, but I seem to remember there being one).
So am I! I haven't the foggiest how I'm going to do them, yet; I'm still deciding. I'll probably fly by the seat of my pants for a while - life's more fun that way.
It's actually not as melted from the map as I expected, but I'm definitely melting my brain with all this in conjunction with my schoolwork. It might be a couple weeks before I post here, again. I have a rather sizeable paper due in my music lit class in just under two weeks, I believe, and it is past crunch time. But then, I'm just crazy enough to pull it off if I gun for it, I think. Only time will tell.
