Sorry if some of these points have already been made...I'm too lazy to read all gazillion posts.
I have the FastTrack interface, Protools Essential, and the AV-30 speakers. Love it all! But there are some considerations:
Avid's Win7 64-bit drivers suck. After messing with every possible setting and reading tons of forums, I ended up dual-booting Windows XP 32-bit, and it works perfectly. It may be a 64-bit issue vs. Win7, so 32-bit Win7 or Vista may work. The main issue was lots of pops/hisses, and high latency, which makes syncing multiple tracks virtually impossible. Save yourself some trouble and install on a 32-bit system.
Don't expect to use the mic with the FastTrack interface. The mic is USB only, and you need an XLR mic for the interface. Also, this mic is a condenser mic, which requires phantom power. This particular FastTrack interface model does not have phantom power, but the mic is able to get the phantom power it requires via the PC USB port.
The speakers are phenomenal! I actually have them connected to the FastTrack via the stereo RCA jacks for when I'm recording in WinXP 32-bit, and then when I'm booted in to Win7 for other tasks, I connect to my PC sound card via the front AUX jack on the speakers. Works well, and only one set of speakers on the desk.
Protools is an incredibly powerful piece of software, but if you are unfamiliar with recording software or mixer boards, be prepared for a learning curve. But once you get it down, you'll be amazed at the power and versatility.
Here's a link to some of the recordings I've made using the FastTrack and Protools: http://www.set4e.com/Songs.html
For comparison purposes, the first two tunes on the site were recorded with Protools via the FastTrack USB interface and a quality vocal mic. The second two tunes were recorded using a chap lapel mic and Audacity. You'll hear the difference in a hurry.
