Ask HN: Incorporating in USA (nonresident)

I am opening a company (C corp) in US for my webservice. I am European. Any information / opinions on these questions are very appreciated. I am sorry if some of these are stupid. I talked to a lot of people, read on-line stuff but certain things are still not 100% clear.

1) I intend to open it through www.bizfillings.com . Their site looks legit and packed with information. Any experiences?

2) Delaware or f.ex. NY ? (does opening comp. in Delaware make you suspicious/border-case in your country? I have no "evil" intentions, don't care for tax after profit that much, do care for running expenses, complications, bureaucracy)

3) I will have 2-3 advisors with 0.5 - 3% stock and one helper with 12%. Is it cheaper to make the deal and give them shares before formation, or can it be easily/cheaply done after it. In what range are the (legal/bureau.) expenses associated with this after formation (I know angel deals cost 5-15k)

4) what do such advisors usually prefer: shares, options, ..? What is the simplest, cleanest way to do this. I want to include some vesting terms too. I intend to talk to them of course, but I would like to know more about it when I do.

5) How to open a Bank Acct. I heard it's hard to open it unless you physically come to and US bank (some say it's even harder after patriot act..). Can Bank Acct. be opened by a third person that would go into US bank with mandate from me? Would it-help/he-have to be one of the owners/officers of the company?

That is all for now. I hope your answers help others too.
