One other thing to consider is a CLA- if you plan to accept contributions from outsiders, and you stick with AGPL+Commercial, you will want any contributors to sign a CLA that grants you the right to sell their contributions under the commercial license. This would be a hard stop for me, and others like me, to contributing to the code... but is necessary if you want to accept outside contributions while offering a commercial license option. (Another good reason not to use the AGPL, if you want to encourage community development- many commercial open source products simply forbid outside contributions of code, though, or don't care about outside contributors).
