Transfer Hosts

I'm thinking about transferring hosts and going to something that will allow me to use my own domain Utills.com to host my blog. I need to add some other stuff too so I'm looking for suggestions on what host to go to and how to do it so that it reads from my Blogger database?

Does anyone know if I lose my pagerank ranking even though in majority of places online my domain Utills.com is linked rather than utills.blogspot.com?

I've noticed that majority of the blog search engines do not have any of my latest posts...are they slow in updating? or have they started to ignore blogspot due to the large number of splogs (spam blogs)?
