I  just wanted to add a few things in addtion to above.  first I am a consultant and see alot of migrations and broken networks.  So this is based on my experiance and opinion.

1 Veritas Backup Exec 9.1 works really well on 2003.  Plus they have a very cheep "competative upgrade" option.  Arch serv is fine but Veritas in my opinion is easier to configure, manage.  I also feel better about the restore ability of Backup Exec and that is what counts.  

2 Anti Virus soluton to look at is Trend Micro's Client, Server, Messaging suite for Small and Medium Business.  If your not comfortable with the SMB look at there Enterprise products.  They are very easy to install, manage, deploy, and monitor.

3 read this white paper but, your on the right track.

All looks great except for
"Install Exchange 5.5 as part of the same site as the current Exchange Server"
I wouldn't put another Exchange server into the picture, install ADC and transfer mailboxes direct from old Exch 5.5 to new 2003.
Otherwise all looks good, I have done a lot of migrations in basically the exact same order and recommended the same steps in a few previous questions posted here.

We use ARCServe and Veritas on different client sites.

but find Arcserve more stable and easier to diagnose problems when on the few occasions they occur.

I try veritas each new edition but find myself returning to arcserve each time.

We also use symantecs Corporate edition and will continue as have not seen a major reason to move away from it.

As I have seen said before, sometimes it is not a question of which product is better (as they are both good in both those categories)  but which product you know better.

I have a client that tried to save money (on antivirus, with AVG) and ended up regretting the configuration and management issues that came up and we are now back to using Nortons.

Thanks fo the article
