What Would You Recommend? (setup)

Hmm where to start..
Ok here's what I've got
Digi 002
G4
Studiophile Monitors (xlr and trs inputs)
an older pc (let's assume it works fine) with 256mb ram, blurry monitor and crappy sound card (it's a compaq presario mv500)- needs upgrades but good for fruity loops, cool edit a reason.
yamaha aw16g (2 mic ins, 6 line ins, L and R stereo/aux out, L and R Monitor out and Phones
out.
a fairly decent set of headphones.
shure sm58 mic

Now here's my issue, and I'm sure it's less complicated than I'm making it out to be lol but...
I'd like Pro Tools to be my primary setup, how can I still use the aw16g and the pc with this setup, without having to go behind everything and switch a bunch of cables around? do i still need the aw16g? i don't really like the mic ins, the sound isn't that great but maybe for getting sound from the pc? is there a way i can use the monitors for both boards, the 002 and the aw16g- do they make trs to xlr cables? Is there anyone out there with a similar setup?
TIA,
ODD
