Hardware and software requirements are documented at http://www.cisco.com/en/US/products/sw/cscowork/ps2425/products_qanda_item0900aecd807116be.shtml as well as in the LMS 3.0 installation guide.
Yes, your current data will migrate into LMS 3.0.1.
There are no systemic problems affecting an upgrade from 2.6 to 3.0. Though a typical caveat exists for Windows that you should set your global and per-user TEMP and TMP environment variables to something short like C:\WINDOWS\TEMP prior to doing the installation.
