Google questions

can anyone answer me these?

I'm trying to get to grips on how these search engines work and after reading a lot of the Google topics I now need some things clarifying:-

1. I keep hearing mentions of 3 servers. How do these differ and could I be in all 3 or just 1 of them. Or does it depend?

2. What's the Google dance? I believe from reading some posts that its when they change servers but does it happen regularly at a certain time or is it random?

3. Google crawl. Is this every month?

I really appreciate any answers to my questions, I have searched for them but ended up confusing my brain ;)

Cheers!

Ooh, also people keep talking about page rank on the toolbar (which I have). What is this and is it in any relation to ranking on searches?

Thanks so much!
