I think this is coming along very nicely Vandy.

The floor looks fine to me, I don't really see the 'tiling' and for on a floor I don't think it s a big deal. For the walls, if you used a pattern overlay you can try re-scaling the texture to see if that helps break up the pattern some.

Hope you get things squared away on your PC soon so you can be back to mapping at full-power.
