Distaster Recover

OS: Windows 2003 Standard Edition
MS SQL: Standard Server 2005

I am looking to implement a disaster recovery plan for an MS SQL 2005 server, this is what I have done so far but would like the benefit of your experience to provide feedback and help improve the strategy.

MS SQL Server:
I have two maintenance plans, one to backup the system databases to individual backup files (.bak) and one to backup all the user databases to a backup device (mssql_backup) The backup files & device are in a directory (backup) and is backed up using NFS. I keep a copy of the backups on a USB HD which is stored offsite.

Disaster:
Office burnt down

Recovery:
New server, install OS/MSSQL, patch up to same version as burnt server.

Copy .bak files to new server, copy mssql_backup file to same location as previously held i.e. X:ackupmssql_backup

Start MS SQL in single user mode, restore master database using .bak.

Start MS SQL in normal mode, restore other system databases using .bak

Restore user databases using mssql_backup device

Testing:

Using the above steps I was able to restore up to the point of "user databases" Getting to this point I realised that there are a number of databases to restore, in my novice ways this seems to be a lot of right-clicking and restoring.

1) is there a command that would in effect be able to restore all databases using the backup device?

2) do I have a working version of the databases to the point of the last backup? Or am I missing something?

3) in my current setup in mind (SQL backup to NFS directory and picked up my backup software) is there a 'better' way I could be doing this which would make the restoration procedure more efficient
