I'm looking to build a 22LR upper from CMMG.  I already have an upper receiver and handguard.  Are these all the additional parts I'd need to get this thing running?

 
Barrel and Collar Kit, 4.5" MT 4140CM, 22LR
 
Bolt Group, 22ARC
   
Ejection Port Cover Kit, with Gas Deflector

Charging Handle Assembly, 22ARC

Magazine, 22ARC, 25R3

Go with a Taccom barrel and collar kit & their bolt group. You will have an upgraded and coated bolt through taccom. Don't need the ejection port cover kit nor the charging handle, so you can save some money there if you already have standard ar 15 ones. As for magazines, skip CMMG mags all together and get either Black Dog, or go with the Better-mag adapter and S&W 15-22 magazines. Imo the 15-22 mags are the best in the business.
