Well, I may never hear you say THAT again, so I'm getting in this one...
Strike Industries for the charging handle. Primary Arms has a very decent price for it, but if you want to shop around, search for THIS ONE...

Id say this, though - on something with a magnified optic, and extended latch makes it a HELL of alot easier, so I'd search for this one instead, for a few bucks more. This is straight from Strike, but you can look around. I'll try to find something cheaper on it - but Primary Arms doesn't seem to have it right now... This bitch, right here:

Here's the extended one on Optics Planet for $42 - scroll down:

VG6 Epsilon 65 is a badass muzzle device, good choice. If you found it for $66, snatch it. I see it for $72 at a few places, and my price on Brownells for it is $65 - so if you found it for $66, getthe damn thing already. It's a $100 brake.
Here's a $15 gas block:
