Yep, you need 1st gear, 1st gear baulk ring and the 1-2 synch sleeve. Which basically means you need a trans rebuild. Probably should put all the baulk rings (synchronizers) in at the same time. Look at the bearings (you can get an aftermarket bearing kit with all the seals included as well) at the same time.

As far as the clutch hangine up, you may have a worn nose cone. It's what the throwout bearing rides on. A new one is probably in order.

Get a new clutch while your at it. Clutch, pressure plate, throwout bearing and pilot bushing. Be sure to have the flywheel resurfaced, stepped, of course. If you off road it, then you may consider getting a heavier duty clutch, with a stronger pressure plate, and a little beafier disk.
