The protolanguage has four stop series - labial, dental, velar and labialized velar. Does it make sense to shift the latter unconditionally to a uvular series?
Yes, I think /k kʷ/ > /kʲ k̠/ > /k q/ is entirely plausible. (It might not be too likely, but that's another matter.)

Yes, I think so... /p* t* ts* k*/ (using * as an ad-hoc faucalised diacritic) could probably become either of ejectives or implosives, and I can imagine /nˀ lˀ rˀ/ turning into /ɗ/ which might then merge with whatever /t*/ has become. If the glottalised resonants remain what they are, analysing them into "the same series" as glottalised plosives probably depends on what other phonemes exist in the language. For instance, if the entire consonant inventory was something like /p t ts k ʔ s n l r p’ t’ ts’ k’ nˀ lˀ rˀ/, where only /ʔ s/ do not have a counterpart with the opposite glottalisation value, you could definitely analyse all [+glottal] consonants as a single series.
