rdorman,
Are you sure you've got sufficient clutch release? Like Mr Fixit asked, does it go into gear (particularly reverse) from neutral (with foot off clutch) without grinding?
First, if you have to pump it or if pumping the pedal helps the shifting, it may need a serious bleeding.
Second, check the "free" play at the pedal (between fully depressed and the point when the clutch begins to engage and the car starts to move)...should have at least an inch of pedal travel from floorboard to point of engagement. If not, check the linkage adjustments. Make sure slave cylinder is at or near beginning of stroke (topped or bottomed out, whichever yours uses) and check the clutch arm stroke (at the bellhousing) - should have 3/4" or so at the end of the throwout arm.
Good luck.
