I want to put together a home studio so that I can continue to be involved in music independently of my band. I'm lucky enough to be getting a Macbook as a belated birthday present (

Initially, I just want a set up that will allow me to track instruments individually to some level of quality. The problem is, my knowledge of the products on the market is completely minimal - I've just made up a google shopping list that I reckon will be enough for reasonable drum recording, as well as any other normal small instrument. It looks like this :
Focusrite Saffire Pro 10 I/O firewire card: £295/$550
SM57: £75/$140
SM58: £75/$140
Shure Beta 52A: £150/$280
2 Sennheiser E614: £235/$440
Stands, leads and shit: £100/$185
Grand total: £930 / about $1700
If anyone has any advice in terms of items that you'd consider to be missing or unnecessary, or particuarly cheaper/significantly better value, or any general advice, I'd very much appreciate it.
