Yes, a backup created with MFSTools will include everything you need to recreate your setup - minus the actual recordings.
For a UK machine you need to use the -l32 switch, and I would also recommend leaving off the compression (ie. use -so instead of -6so) as the compression library is buggy and can result in a bad backup. An uncompressed backup file will be around 1.4gb but can be compressed with Winzip for archival purposes.
