I would have used the stock cables, but they would reach up front

I really like the battery up there. I use an Optima which is sealed and fairly heavy. It's nice to add a little weight in the front. The SC3800 will already push the front tires in the corners while accelerating.
Just remember on a "performance" orientated swap, anything worth doing is worth overdoing!
I think I used 1/0ga for everything. Oh, and one can't ever have too many grounds. I see too many swaps with a little 12ga body ground and tons of accessories, such as a stereo with an amp that has 4 ga power wire, and it's grounded to the body, using the 12ga for the entire car and the stereo!
Good luck with everything, you'll love it.
