[LAU] Recording Equipment

Hi LAU! I'm new to the group, heard about it from some random forums. I'm looking into getting pretty much a "starter kit" for recording. I'm considering getting: 2 AT2020 mics 2 XLR cables 2 generic mic boom stands M-Audio Delta 1010LT (PCI sound card) I'm temporarily holding off on studio monitors and using some Sennheiser headphones for the time being. I was considering the Yamaha MG166CX mixer, though changed that to just the Yamaha MG166C (I don't think I need the fx). Though, I don't know if I even need a mixer at all. It seems like people are just using the ones in the programs (like in Ardour). I have gobs of questions to boot... :) Would benefits would there be in using an actual analog mixer with a DAW? I'll be using apps like Ardour, do I need a mixer? Should I get an A/D D/A converter (like the Behringer ADA8000)? If I get a mixer with the "Delta 1010LT", will I need the ADA8000? Does the 1010LT already serve as an A/D D/A converter? What would anybody recommend? I have immediate access to 2 electric guitars, 1 electric bass, 2 acoustic guitars, 1 electronic drumset, and 1 (old) MIDI keyboard. I'm also looking for a MIDI keyboard, perhaps 88-keys but condensed such that I can put it on the desk near the computer keyboard and LCD monitor - intention on the MIDI keyboard is for composing and recording. Thanks! Sean
