The first thing I would recommend is updating to VDL 2.5. VDL:2 uses an older version of the Kontakt Player which isn't technically supported on newer versions of the Mac OS (Leopard and greater). As a registered user of VDL2, it's super cheap to update to 2.5. Just enter your serial number and order here: https://www.tapspace.com/Virtual-Drumline-25-pr-6.html
AU stands for ";Audio Unit."; Essentially, if you're used to doing things in the PC world with VST plugins, AU is the same thing, but just specific to Mac. Mac can also run VST plugins, but in Finale, they only offer AU support on the Mac platform.
Once you've got VDL 2.5 installed, you should definitely consider getting the VDL Template for Finale 2010. Using this, you'll have all the VDL customized mappings that correspond to Finale's new system of handling percussion. Huge time-saver. There are a couple basic tutorial videos that give you a basic overview of the template components here:
I hope this may help give you a little direction as you move forward. If you get stuck, be sure to search around the forums here. Lots of old topics that will help steer you in the right direction, or just chime in with new questions if you encounter them.

Thanks Jim - I'll try all that...didn't know the upgrade was so cheap - I would have done that long ago just because!
