Fix the a/c, get an alignment, and throw a stock clutch in the B14. Keep the B14 as close to stock as possible. Do this first so you have a solid daily driver, you ALWAYS want to have a dependable mode of transportation. Sell it only if and when you need to.
Keep the B13 as long as the tree incident didn't cause you any frame damage. Fix it as you have time and money upgrading to better, stronger, and faster parts. My .02
