20amp circuits with 20amp receptacles
The only reading you need to do is NEC Article 210. Specifically Article 210.21(B) (1) which states that if there is only one receptacle on a 20A circuit it must be 20A. Also 210.21(B)(3) and Table 210.21(B)(2) which tell you you can use 15A receptacles on multiple outlet 20A circuits.

Hope this helps.
