tgreening - I have never heard of it being a big deal to submit multiple form 1's simultaneously. Some people even prefer doing it that way.
Fingerprint cards and pictures are NOT required when using a Trust to purchase your items (tax stamp/s) through. (However don't forget your 922 (g) compliance statement with a form 1 - if applicable.)

Side note - with submitting multiple BATFE tax forms at the same time. Some people will recommend a separate $200 check for each form. Rather than have one check for $600 for three forms, I would go with three $200 checks. I put the SN of the item in the bottom notes section of each check.
