The reflector is called aluminum 'roll' and you can get it at most home improvement stores for pretty cheap. I think its around $5 for 10 feet. The one that is 6" wide works the best IMO. Its pretty floppy stuff when you start out with it flat, but once you put in the bends it stays much stiffer. Stuff it really sharp though so best use gloves if your forcing it. Its sliced me really good before
Rain gutters are not tall enough for vertical mounting. Horizontal mounting works, its just studies with a PAR meter show vertical mounting gives you more light at depth.
I answered my question about powering different bulbs off a spiral CFL. I've only done one, but so far the answer is yes! I haven't really figured out what that means yet or if there is any real gain in doing this lol. I've only tested one bulb. A 13 watt spiral CFL 'driver' can power a 13 watt bi-pin power compact bulb just fine. I might try a 15 watt T8 just to see if it will light, but thats kinda pushing it. I'll probably grab a cheap 14 watt NOT5 and some larger spiral compact bulbs tomorrow and mess around with them. It maybe a lot more technical then you want to deal with.
This is the quick and dirty setup, this is NOT how I would recommend doing things. Just showing that it works. The light bulb socket can be completely removed and the driver wired directly to the power cord.
