I don't have an nvidia card, but my radeon card has vga, digital and
s-video outputs. As for needing two vga, my card came with an adapter
that converts the digital to accept vga, so I don't think that should be
a big issue.
I've not had any success (with X) doing as you've noted, two monitors to
two outputs on the same card. When I boot my machine with two monitors
connected, both screens show the boot info and mirror the console output.
I know of folks who have had success with this card and other ati cards
that have dual outputs. I've been planning on trying a quick SuSE
install just to test this scenario, but haven't made the time to do so.
Understand, you don't really need to spend a lot of bucks for a dual
output card, mine as around $100 when I got it, certainly cheaper now.
It's only got 32mb (only, I remember when that was a lot of system memory.)

3d is not supported for dual monitors on XFree, although the
proprietary drivers for nvidia may well support it. If so, then you're
likely to want a card with more memory.
You have to get a later version of XFree to get 3d to work with the
later ati cards at all.
