Don't forget to listen!
Learn the chords then go back and play along with the track, the rhythm and changes will come alot easier, and you'll start developing an ear which you're gonna need if you aspire to play with others, or working out the tabs for song on your own.
Also if you're trying to play on an acoustic a tune recorded by a four piece band you may have to extend beyond the transcribed guitar part - playing along with the track helps you to find the groove and maybe a little invention will give you the bigger sound that your looking for. When using the track as a backing track you'll soon hear what works and what sucks.
