You can meet other entrepreneurs at a Bootstrapper's Breakfasts http://www.bootstrappersbreakfast.com/ there are three scheduled for August. We get a number of out of town visitors and you would be welcome. The other events you list all look very good, if I had to pick one from those you mentioned to make sure of attending it would be the the New Tech Meetup in Palo Alto. SVASE (http://www.svase.org/) runs a number of events where you can meet VCs: breakfasts, Startup-U, CXO Leadership forum. SDForum (http://www.sdforum.org/) runs 20+ SIGs, I would check out the Startup and VC Funding SIGs during your visit as well as any related to technologies you are working with.
