The final count-down: MI to CA

We've known since February 4th, that we will be moving to CA this summer. As we have gotten closer to the summer months, my transfer from one of my employers divisions in MI to another division in CA has been finalized. I've begun training for the projects I will be working on/overseeing/taking over once I start at the other office. Our last day in MI is June 6th. After work, we'll hop in the car with our two faithful companions (the kittens Linux & Nibbler), and start our week long adventure! We are quite excited. While we are excited to leave MI, and be in a state neither of us have lived in, I am most excited about working in Silicon Valley. I feel that most engineers in the tech industry would be excited about living and working in one of (if not the) biggest tech hubs in the world.

All of that being said, we're looking for tips and recommendations from those the internet. Please feel free in the comments to respond to any or all of the following:

• What are the best sites to see and places to visit in CA? 
• If you were taking a roadtrip and had up-to a week to travel, what route from MI to CA would you take? What sites would you see? 
• In general, what recommendations do you have?  (This will be our second cross-country roadtrip in the last year). 
• What's your stance on tinting windows? Would you/have you done it, and is it worth it? 
• If you've traveled long distance with pets, especially cats (ours are about 9 months old), what recommendations do you have?
• We will be taking videos of the trip, as well as TONS of pictures (last time we took around 600, we plan to beat that). What cameras/camcorders do you guys recommend? (We have two Nokia Lumia 920's (which we love!)  and are trying to decide if it's worth upgrading to 1020's/1520's or just picking up a camera/camcorder (especially since new devices are on the horizon)). 
• Anything else you'd recommend?
