Re: Recording software~
Bludave, Mac and GarageBand is an excellent way to go. Since the software comes with the computer, you are virually ready to go. When you outgrow GarageBand, which could take a while if you're just getting started, you can move up to Logic Express or Logic Pro, which are also Apple owned programs, and therefore integrate seemlessly with the Mac. Logic also integrates with GarageBand, so that you can take any songs you've worked on in GB and import them straight into the more powerful Logic. You can also use the library of loops, drumkits and sounds that comes with GB in Logic. You will eventually want to get a dedicated audio interface, which will vastly improve the way you record, especially using mics and external sound sources.
I made the shift from recording console and dedicated hard disk recorders/outboard rack effects to computer DAW about two years ago, and it has dramatically improved both the workflow and the quality of the recordings. A drummer I work with recently got a Macbook (laptop) and while we were away on tour, he asked me to show him how to use GarageBand. I showed him about three or four things in the space of 15 minutes. An hour later, he had made up his first song just using GB loops and sounds. He even had some vocals recorded using the inbuilt mic. The Mac makes the whole process a lot of fun, you'll be impressed.
