Networking newbie question: how do I set up a Cisco router-based VPN between three sites, such that each can treat the other as if it were on the same LAN?

Right now, I plan to use a Cisco RV082 and two WRVS4400Ns at locations in three different states. I need to set up a VPN tunnel between the devices. That's where things get fuzzy: my previous networking experience is basically just setting up home wireless routers. I can follow Cisco's tunneling guide until it starts asking me for my 'preferences.' I find I don't know enough to have articulate preferences.
What do I need to know? For instance, do I need to use a 'subnet'? What's the best encryption option? Also, what questions should I be asking? What issues or problems should I be on the lookout for?
Basic setup: three homes. One has a home server, three laptops connected wirelessly, one ethernet-connected desktop, and a couple of media extenders. The other two each have an ethernet-connected desktop and a laptop or two connected wirelessly.
