Manual of Nearctic Diptera includes a key to families of fly larvae. Identification to genus, or of first instar larvae, will be difficult. MND does not have larval keys for the major carrion feeding families.
Books on forensic entomology should offer more details on the common species in human bodies. I have not read any of them.

One title, quite nice, but there're many : 'The science of forensic entomology (D.rivers) - 2014" . But for some very specific ID, you need specific books .

Some general books on larvae/pupae
Smith (1989):

Apparantly Smith also wrote:
Smith, K.G.V. (1986). A manual of forensic entomology. London and Cornell. (I do not have this)
Ferrar (1987). A Guide to the Breeding Habits and Immature Stages of Diptera Cyclorrhapha. Entomonograph 8. Could find't it online and I do not have this, but I have seen it and made a few copies of the aquatic stages of some families.
and maybe Skidmore (1991) can help although it is on dung species
Skidmore, P. (1991). Insects of the British cow-dung community

Furthermore, I know of two Dutch researcher with knowledge on forensic entomology (Hans Huijbrechts and Jan krikken) ; , maybe they can help you further.
good luck
