The glossy paper is the type used to get nice colour laser prints, the gloss is actually polished clay same as glossy magazines. Usually they call it Gloss Color copy paper, it is not ink jet photo paper. It can be bought at your bigger office supply stores in A4 quite easily, I also use A3 for my power pcb's to get full coverage of the 200 X 300mm board, the A3 is much harder to find.
I have found the surface scratching does give far better adhesion, the amount of copper lost is very minimal.
As for question 2, I do exactly as you have quoted, only thing I have found is that if it is too hot the toner will start to spread under the pressure of the laminator rollers. I use a Kyocera colour printer/copier, other machines with different toner may have different temperature requirements.
If you wanted to after drilling the PCB you could print a silkscreen and transfer it on the same way, I have found it to be fairly robust but will scratch if anything sharp comes in contact with it.
I have had no issue at all using Acetone on PCB's, is quick and removes the toner with very little effort. After drilling I use Oztules tip and spray lightly with Lanox and wipe with a cloth, it prevents oxidisation and aids soldering. If you put it on prior to drilling it makes the drill shavings stick to the PCB.
