Simpsons yeah, I cracked up when I first saw that episode...
Traxxas forum is full of idiots, I mean the worst kind who just dont know anything, cant figure anything out for themselve, and have to be spoon-fed info and advice, despite me writing several help threads and FAQs etc (which few bothered to read or look at). I got banned eventually as they just drove me insane asking the same questions every few hours- blew my top once to often.
That lipo saver looks fine- I have seen many that are very similar, and have a couple myself that work roughly the same way (3.5v per cell is little bit high for the cutoff value, but since its what BrianG would call 'passive' alarm, it wont actually turn the truck off, which is the way I like it too).
The lipos are great too- I have heard of Stefans lipo shop before, very good lipos apparently.
if you mean the threaded portion that goes though the middle of the wheel, it does look a little fat, but I think most larger hexes are like that, so that the lock-nut has something substantial to screw onto; if it was too thin, it might snap a bit too easily after jump or bump.
The Maximizers have a fairly good reputation, but sometimes even they arent enough to keep the tires on the rims, depends how fast and hard you drive, and how much the tires tend to balloon- wrap some gaffer tape around the inside to reduce ballooning.
I dont use the bumpers myself, I have a Hardcore Racing Titanium front skid that I prefer, much more durable and makes the truck look less like a toy in my eyes. There are several companies that sell aluminium bumpers though, like Integy or Traxxas. RPM sells a really good plastic bumper though thats popular:

Those are pretty much indestructable- the mounts or bulkheads will break before they do usually.
