Great man you have some shit hot prices.
If you dont go for Digidesign products, you could look over M-Audio Delta 1010, Motu 824, or Echo Layla. All 3 simple interfaces, they all got a few in and out and expandable capacities, all 24/96 compatible, and, great lookin and practical rackmount format.
(Personnaly I looooooove rackmount format, so clean in a studio, I hate little boxes always movin around lol!!!)
Believin you got some nice price like that, then you could buy some good monitors like Mackie Hr624. Check the price he can make you. Or the other monitors you can look for are the BX8 From M-Audio. Great product. Yamaha MSP5 too or MSP10 if you can afford, excellent monitors.
Like I said Rode Nt-1000, AKG C414, C12, Neumanns, there's a lot of great mics out there.
