When can I request a 32-bit ASN?

You can request one now. If you do not specifically ask for a 32-bit ASN, you will receive a 16-bit ASN. However, as of 1 January, 2009, all assignments will be 32-bit ASN by default, unless you specifically ask for a 16-bit ASN. From 1 January 2010, there will be no differentiation between the two varieties and the RIPE NCC will assign from a single pool.
