Answer 1

I created a google site of my own, uploaded 1500 files and wrote google apps script (similar to yours) to replicate this issue. As it turns out, I too am not able to retrieve files after the first 1000. This is happening even if I change the start-index and max-results. The only reason I can think of is that this is an undocumented limitation. There must be a limit of 1000 for the number of attachments. I might be wrong.
The limits for attachments to a Google Site are mentioned in this link - Storage and file limits
