Wayne, We have a couple of DD690s (1 Appliance, 1 Gateway) and I've really got only good things to say about them. They're easy to setup and configure (VTL and NFS).
You might want to consider what your retention periods will be for the data you keep on it. We use 3 months max for the VTL, and anything over goes to Physical Tape for offsite storage. At www.datadomain.com there is a pointer to a Best Practices guide for Netbackup.

The plan is to write from the vtl to the smaller library and send offsite.

Personally, I would be uneasy with this, because in the event of a catastrophic failure with your VTL (as highly unlikely as it is) your backups are gone. If you are a smaller shop, this risk is acceptable. On the upside, the performance increase is going to phenomenal. We just replaced a non-deduping EMC VTL with a newer one. One of the things that NetBackup required was to actually emulate the EMC virtual library. Otherwise, you will run into some licensing issues. No biggie, the EMC could emulate as many drives and as many tapes as the physical disk storage would allow. There is probably something similar with the Data Domain.

We are looking at purchasing a Data Domain device, eliminating the SureStore library as it is at its end of life and replacing it with a smaller library. We have no experience with a VTL or what pitfalls or things to look out for while setting up the new environment. Any advice on where to look to gather info, or experiences of what to look out for? Thanks in advance.
