Yeah, I know - I'm really lucky!
We will indeed be renting bikes in Barcelona and will ride around for two or three days during our nine-day stay. The mountains north of Barcelona are supposed to have great motorcycle roads!
Thanks for the recommendations. I actually managed to contact Tanya Wicks via email. She's the marketing coordinator for SBK international. Turns out I can buy tickets through her (she's in England) or through the Valencia track itself. I think I'll go with her since I doubt I'll be able to make myself understood to the ticket drones in Spain.
Just for the record in case someone searches for this thread later on, here is the info she sent me:
To purchase normal entry tickets you have to contact the circuit
directly. (these are standard tickets which will have grandstand
and allow you only in the public areas). The circuit can be contacted
tel: +34 962525220 or www.circuitvalencia.com
Through me you can purchase paddock passes (valid for all three days,
allow circuit entrance, grandstand seating and entrance to the
SBK paddock). These cost US$110 per person. Alternately the hospitality
package as outlined on our website www.worldsbk.com
Club' for US$400 per person for the weekend.
Please let me know if I can assist you further.
