Do I have to/need to get new gears if I swap my rear end for a posi unit? I'm guessing the gears would become the weak point if I reinstalled the stockers? I've got a stock open spool now and know I need a posi. I just don't know anything about the gears. What are some good ones to get? Thanks!

The gears are fine. Re-use them with the new posi unless you just want to change the gear ratio.
