Second Q: How many AS numbers are available in total?Currently an ASN is a 16-bit number.
And a whole lot (~1/2) are reserved to IANA. Specifically: 32768-64511 IANA-RSVD 64512-65535 IANA-RSVD2 You can find this on ftp://rs.arin.net/netinfo/asn.txt (even if it hasn't been February ;). The second block is the one you have to worry about since those numbers are used for things like BGP confederations. I believe the first block could be allocated to the general public, but you'd have to check with someone more cluefull to be sure.
