Case 350B shuttle/hydro leaks

1. I parked my 350B when I finished my house a couple months ago. Today I started it up and it barely crawled forward. Reverse is fine, but after about 10 feet it stopped forward completely. Charge pressure gauge works and was reading low. Anything to check first.

2. I have a spool valve leaking(picture attached). I've never rebuilt a spool valve? could someone point me in the direction for which parts I would need? Thanks guys
