To qualify for an 'L-1' (Intra-company Transferee) visa you "must be at the managerial or executive level, or have specialized knowledge and be destined to a position within the U.S. company at either of these levels, although not necessarily in the same position as held previously".
See here for further information:

Otherwise you'd need suitable qualifications, at university degree level, to try to convince the immigration service that your employment satisfies the criteria for a 'speciality occupation' (for which you need a 'H1-B' visa). See here:
http://www.usembassy.org.uk/cons_new/visa/niv/ work.html
You need to be aware that the US authorities frequently take many months to process visa applications, so you should apply as early as possible.

PS: The best way to find out about housing, etc, might be to make direct contact with some of your future colleagues by email.
