First gear skips when releasing the clutch

Most likely not. More then likely this is the clutch itself is failing as a result of the throw out bearing. This is what is responsible for engaging and disengaging the clutch when you press the pedal.

Here are a number of guides that will help with this:

If it were me, I would go ahead and replace the entire clutch rather then just parts of it. You only want to go in there once so I would just make sure everything is new.

We don't have a manual on this vehicle but if you want to, you can let it go and see how much more use you can get out of it. Once it starts to get hard to put it into first gear, you will want to go ahead and replace it so that it doesn't leave you stranded.
