B. Which is the best modchip? I'm wondering about ease of installation mostly, because while I'm fairly handy with a soldering iron, surface mount terrifies me. Any other critical differences noted would also be nice.
It's debatable but most people will either recomend the Qoob or the Viper GC. I personally like the Qoob better because it seems to be supported better. the Qoob comes in a Cheap "SX" version and a more expensive "Pro" version. the SX is cheaper then the ViperGC and the Pro is more expensive then the ViperGC but also more feature filled.
Installation is a breeze, it's easier then installing an Xbox or PSX modchip thats for sure, probably one of the easiest consoles to mod. You'll have a harder time opening the damn case then soldering the points (at least I did).

C. Which is the best aftermarket case for full size dvds? I've heard rumors of some of them scratching discs, and I was curious.
I can't tell you because I use Mini DVDs... they've come down in price quite a bit and are only a few cents more expensive then full sized DVDs now anyway. The GC DVD drive is VERY VERY picky. using Ridata G04 mini dvds with an NEC burner has produced awesome results with my GC... IMO it's worth not dealing with the DRE headaches and just going with the mini dvds. some will beg to differ but that's my opinion. (becides nothing looks and feels more like the stock case then... the stock case)

D. Looking at some of the install pics, I see that there is something plugged into the expansion port. I was also thinking about getting a bba, so what would happen if this thing was unplugged from the expansion port? I think it was the usb interface, but I'm not sure.
I have no idea what you're talking about. I have a BBA on my GC and I don't recall ever seeing a GC modchip that used that port

The GC has several expansion ports on the bottom and I know one or two chips use that AREA to feed out a ribbon cable though one of the other (not the BBA) ports but AFAIK it doesn't interfear with how they work.
I'd also recomend reading this writeup I've made:
