Dual boot is not going to be a problem. I don't use Trisquel, but I do have like 30 distros for BSD and Linux in virtual machines, so you just gave me a new one to try out.
Now, GRUB supports booting any number of machines, I have quint-booted before Mac, Ubuntu, Windows XP, Windows 7, and PC-BSD.
Trisquel apparently uses GRUB as it's bootloader, so after you partition and install it, GRUB will see ubuntu as well as trisquel so you'll be able to freely boot into either one you want.
I'm looking at Bodhi for the same reasons you're looking at trisquel by the way. I'm NOT digging canonical's direction with the whole auto-opt-in CRAP, and I like debian-based distros... check Bodhi out man, I like it. I'll give Trisquel a try for sure too.
EDIT*** Your second question... no, you won't lose any drivers. since it's a debian-based distro, trisquel would require similar, of not outright the same drivers. debian packages work on nearly all debain-based distros (or even converted .rpm or pacman, etc... the only universal linux package is a tarball), so you should be more than okay. I'd imagine trisquel has it's own method for finding the drivers you need to. As long as you have Nvidia, you'll be MUCH better off than having ATI, linux support for thos cards freakin suck compared to NVidia. Integrated graphics, wifi, ethernet, etc should all work fine - linux has come a LONG way and works almost always fresh out of the box with most distros now.
As for the forum, I'm not so sure man. Fedora, Ubuntu, Debain, Arch, Slackware, etc. have excellent support because of how big the distros are. BUT... being debian-based, you'll probably be fine in any of the major forums off-distro talks. Just mention what you're on. I've never heard of trisquel, but distros are pretty similar. Now, if you'll allow, I'm off to download trisquel.
