Answer 1

I can only really provide insight to part 4 of your question with these snippets:

There are a few guidelines in the App Store Review guidelines (requires login) that mention "web"

2.12 Apps that are not very useful, are simply web sites bundled as apps, or do not provide any lasting entertainment value may be rejected

2.17 Apps that browse the web must use the iOS WebKit framework and WebKit Javascript

12.3 Apps that are simply web clippings, content aggregators, or a collection of links, may be rejected
