From what you are describing, phonegap would work really well. Easier to maintain that ways. You would need to get into more specifics to work out what features you may miss, but for a CRUD, it should work out well.
The goal should be to customize as per the company or person you are sending it it. Its after all a way of learning more about you, in the appropriate context.
I think a short resume that goes exactly in what experience they are looking for would be best. Saves time, and at least shows your focus.
I completely agree with this, to the extent that I enforce this in every place I plan to work with/in. Work in with a small contract, get to know the people/business. Keeps options open for both sides without losing out on time/momentum.
