Well, those are all skills that take a lot of work to develop. But for starters you can use something like Guitar Pro or Tuxguitar and play along, or mute the instrument you're playing so you "replace" it with yours. Or just download MIDI files. This is the least effort solution, but it might be just what you're looking for. If you want stuff to sound better or more professional, you'll need more expensive programs, and you'll need to invest a good amount of time in learning them. (Just having nice programs doesn't make you sound good--you can sound terrible with $1500 of software!) Right now I use Logic Pro + Halion Player + NDK for drums, Garritan Personal Orchestra + Kontakt Player for orchestral stuff, and I play bass and guitar which I also record in Logic. And I use Logic for mixing and such. This is all on a mac, FYI. I don't know what you'd want to do, yourself--that's just me. There's certainly a lot of other software you could use, for example.

It is also important to test your equipment and settings before recording. This will help you ensure that your audio or video is coming through clearly and at the right volume.
