Regarding Ellis Island records try the following site:
www.ellisisland.org/
You should be able to obtain a copy of the actual ship's immigration record.
Another site giving entrants to the USA is
http://olivetreegenealogy.com/ancestry/free.shtml
This site offers free access to records from time to time so keep an eye on it. I think it now offers Philadelphia and New York entrants.
Good luck hunting.
