Yes, you're right. The PIX does not support VLANs.
Your setup will work. You only have to understand traffic flow between both VLANs. Your setup will also work with a 515 bundle.
The only question mark I would place is the use of one switch for 2 seperate networks. Although you defined two VLANs, you put your trust into a layer 2 security. VLANs have never been built with security in mind and should be used carefully. I recommend to use two seperate switches, one for each DMZ network.
Let me know if you would like some more information regarding your configuration.
