I'm not an iptables expert, so I'll defer to others.

What I should have said is that running a VPN client and TBB on the same
machine will route Tor through the VPN.

It's the transparent proxy setup that complicates matters.

The more the better, I think. How much of your 10GB per month limit do
you typically use? Devoting about half of your limit to file sharing
seems reasonable.

But 10GB per month is only about 30Kbps 24/7, which probably wouldn't
help too much, given that Tor typically hits 1-2Mbps. You could only run
the file sharing app while using Tor. And you could also limit Tor
bandwidth, as painful as that might be.
