Font issues in OSX/FontAgent Pro

I'm trying to get a handle on font messes spread across several Macs running 10.7.5.  Lots of different fonts loaded into local hard drives, causing much confusion as we share projects and media on shared storage.  I've been trying to use FontAgent Pro's Teamserver central font library app to get around this, but as I test, I keep getting different and inconsistent results.  For instance, I just enabled one font in FontAgent Pro, and used it successfully in Photoshop.  I then quit Photoshop,  enabled a second font (same family--Helvetica Neue), opened Photoshop, and...it still only sees the first one I enabled.  Aaagh.  Similar results in other apps.

My plan is to disable all unnecessary local fonts (which I did, using FontBook, and it was manual and tedious), and rely only on FontAgent libraries, but now I'm confused.  Any other ideas about how to minimize local fonts and get best results from FontAgent Pro libraries?

thanks,
