SQL Agent Questions

first one is easy: see the Symantec NetBackup™ for Microsoft SQL Server Administrator's Guide for details

The database move redirects the restore of a SQL Server database to a different
location. The new location can be a different instance on the same host, a different
host, or a different file path. The move operation also lets you restore the database
under a different name than the original one.

second one is better asked on Microsoft forum

It's better to avoid a full+log backups situation, bad things can happen :-)

1. Perfectly supported. Steps are described in NetBackup for Microsoft SQL Server Administrator's Guide http://www.symantec.com/docs/DOC5173  

2. Specify both scripts in the same policy. First script (Full backup) will complete before 2nd (Transaction log) script starts.
