1996 Geo Metro Shifting into first feels rough, along with

Hey guys, 96' Metro with 66000 highway miles. I just bought the car and just recently I noticed first gear felt rough. From a dead stop with the clutch to the floor, shifting into first feels rough. It's almost as if there is something blocking me from going into gear or it will feel like it moves into gear in rough gaps. Twice so far I couldn't shift at all and had to go down to second then back into first and it went in no problem. Also, if I put it in first from neutral, then back to neutral, and back in first with the clutch compressed the whole time it will go in smooth after the second time. Other times from a dead stop it will go in smooth as butter. Another thing I noticed is that if I am at around a 2mph roll and put it in first it will go in no problem whatsoever. Lately, other gears are feeling a bit "crunchy." It's on the original clutch and now the clutch engages at the VERY top of the pedal, to the point where I cannot accelerate until the pedal is fully released. Once in gear it doesn't slip at all, but there is not really any grab point. And another problem that happens periodically is that it grinds when I put it into reverse, and other times it won't go into reverse at all (that blockage feeling). It didn't do any of this when I bought it 1,000 miles ago.

On another note I recently began noticing that when I press in the clutch I hear a "psshh" sound, sort of like air being released, it's odd and only does it when I am moving. I tried this at a stop and no sound was made, it's only when I am moving with the clutch in.

There are three things I could think of are the synchros, clutch almost gone, or a simple adjustment. If you could help I'd greatly appreciate it.

Another note, I just replaced the transaxle fluid with the recommended weight and grade gear oil. (75W90)
