If anybody's interested I can provide a list of recommended literature from Russian 2ch thread created by some Sumerian enthusiast. The reason why I picked this textbook despite it being a bit dated is that it taught cuneiform and not just transcription.

Lesson structure is pretty standard - first it introduces the new vocabulary. Sumerian script is syllabo-logographic, so depending on the context a character may designate a word (logogram) or used as a syllable for its phonetic value.
