Mastering is just the final tweaks to a perfect mix before release and should be mastered accordingly to format. Imo, if you've got a one off track going to vinyl it's worth paying a pro to get it right (and I'll plug Ant who has golden ears

No harm in learning about it though, the SOS archive used to have some good stuff and should be available online still. Personally, I'd use my time perfecting my mixing though as it'd yeild greater overall results.
IMO, I think 'mastering' your own music at home is a waste of time. Practicing good mix downs is what you want, with maybe a bit of light bus compression.
Once you get good at eqing and have your mixes sorted, you can play around with a mastering chain, but you are usually better to sort problems out at the mixdown stage.
