The Burton Clash with the Freestyle bindings is a good entry level setup.
I am not sure what the other people are talking about, the Clash is not an advanced board. It is going to be good to learn and quickly progress on, it has a loose rocker shape, and what Burton call Cruise Control, which are slightly raised edges, which just means less catching and more fun.
If I were you, I would choose to get something like the http://bindingreview.com/union-contact/ Union Contacts rather than the Freestyle - overall the Freetsyles are quite cheap and simple, if you have the money to spare I would get the Contacts, which are a higher quality.
As for boots, although there is no real reason to only stick with Burton brand things, have a look at the Hail

They are comfortable, and you won't have a problem riding all day in them. Whatever setup you end up choosing, get the best boots you can afford, it is no fun having a good board and bindings and boots that hurt or don't fit, it would ruin your day.
