Transmission Problems

[sx_coupe]

Hello, i have a 1992 240SX Coupe manual. A week ago or so my clutch went nuts and started slipping. The next day i started it up, pressed the clutch down hard a few times and it was running like new. So recently it started to make it a headache to put into first gear, but only at a stand still. If i'm rolling at 1mph and shift into 1st from neutral it pops in great, if i'm at a stand still most of the time i must put it in 2nd, then first. On some occasions i start the car up, drive it around without a problem getting into 1st. The inconsistency makes no sense to me, please help.
