Focus on the key questions

Your original list is too long.

Some of your questions do not need to ask in the interview, you will find it out later, for example will they give cell phone or not, who care.

Use the limited time to ask the key questions you care about the work and use chance to sell yourself while you are asking questions.

About the title, you can negotiate it after get offer in hand, not now. It is too early to ask change title now. He may not hire you if you ask. (He may chose to hire somebody happy with the Jr. title.).

Anyway, you may not have time to ask all those questions.

Even you ahve time, don't ask the question you really do not need ask...
