I suppose that implies that I can "double spend" my ETH that were bought pre-fork, then? Where can I do this?

You'll need to use a splitter function. Shapeshift.io has one available. You will need to set up a new ETH and ETC address beforehand.

Kinda. You can't do a regular double spend, where you spend the same currency twice (And thus get twice the value out of it, kinda). You could spend the coins in ETH, and then spend the coins in ETC, two different currencies worth different amounts. The catch is that there is no guarantee you come out ahead, like there would normally be with a double spend. The fork resulted in a price drop (That has now somewhat recovered), and ETC is not worth nearly as much as ETH (About a 10:1 ratio). So ETC+ETH is really not worth much more then ETH was originally before the fork, if it is at all - even if you spend both, you probably didn't make any money on the fork itself.

I don't have hard numbers. Let's suppose that you had 1ETH(old), then now you have 1ETH(new) + 1ETC, and you can expend both. The 1ETC(new) in the forked chain and the 1ETC in the unforked chain. But the price dropped, so if you had $1 in the ETH(old) then now you have $0.80 in ETH(new) and $0.2 in ETC, so you didn't get free money, only free tokens that you can try to exchange for money in the right place. (Actually, I guess that the sum after the split is lower because some investor ruined away, so the numbers can be $1->$.7+$.2 or something.) And beware that since both have the same underlaying technology, then some can copy some transactions from one blockchain to the other, because the signature to transfer the coins is the same in both chains. The solution is to make two "tainted" versions of the coins that are disallowed to transfer in the other chain. Read the sibling comment about the "splitter function".
