Do I need to rebuild tranny, or is it a clutch, shift fork, or slave cylinder?

Ok first of all, I appreciate yall's time and effort. Last time I asked a? Here, you helped me fix my car. Well, now I have a geo 5spd manual and my problem goes like this: I ran her hard the other day and I guess I broke something because now she wont drive, btw I put a new clutch assembly on 2000 miles ago myself. Symptoms:

1. With car OFF, I can shift into all gears fine except itll BARELY lock into 1st and 2nd feels softer than before.

2. While cranking(stick and linkage in N), the car moves forward as if in gear, and cant stop her but to turn off the key. Stuck in gear?

3. Finally, when parked uphill in driveway, with no e-brake, she DOESNT roll backwards? But if I push in the clutch she'll roll back? Whats that about?

Anyone that is familiar with manual transmissions I will greatly appreciate any imput you have.
