[Tlhingan-hol] IPA-expert question

[Klingonteacher]

I do understand mostly how IPA works and how to fit it to klingon, but 
few words leave questions open:

1. How do I mark the difference between {paw} and {paw'}. I'm not sure 
if the glottal stop can be used like this: [paw] vs. [paw?] because we 
know that words like these are pronounced shorter. If I mark the 
difference like [pa:w], then I must theoretically add the [:] to every 
word, which doesn't really make sense.

2. What about vowel-ending words?
is that okay: {tI} vs {tI'} = [tI:] vs. [tI?], or only [tI]... ?
