Welcome to the forum.
As suggested about the CPanel transfer is very easy to do and takes no time at all really. The IP changes takes up to 72hrs as it filters out around the world, but this is part of life with the internet, and is nothing to do with us.
With regards to support, there is the wonderful forums here and most of us have experience of an odd package here and there so whatever help people can give, they always give it.
With regards to what package, its true what Bruce says. However, if you start with the smallest one, we can quickly transfer you to a larger one if need be.
Any more questions,please do ask!
