Sorry if this is stupid but is a -CH3 and a -CH2, are they chemically different environments that can be distinguished in HNMR?

Yes. Hydrogens attached to a primary carbon normally have a lower chemical shift.

Google 'OCR A level chemistry specimen data sheet' which the old one from 2008. It has the chemical shifts for R-CH3, R-CH2-R and R3CH separately.
