Hello! I'm so glad you're moving to the Brighton/Hove area! We need more expats down here!! Let me know when you're settled, and I'll give you a tour (but a pretty crappy one, since I don't know much myself... but at least it'll be free!!)
No major tips apart from RELAX. I assume the company is paying for the shipping? If not, get lots of quotes and even ask for quotes on shipping by air. It was only $200 more for us to go by air, so there was no real question. Definitely read the "I wish I would(n't) have brought...." threads on here... they'll help you out immensely.
In terms of adjusting, all I can say is be flexible. Don't fight the differences... just go with it! :-)
Good luck!!!
