1 & 4, you need to install a script to get more detailed "site who" info, as youve found "site swho" is basic, id recommend ioFTPWHODLX
youll get everything youve requested above
3, define your http info in the ioftpd.ini, then simply http to your sites ips, it`ll ask you for a l/p itself (remember httpd was never fully functional to date)
as for 2, maybe someone who uses ioBanana can help you out
