The routers either forward the packet or they don't, right? They don't care
if it is a word document or an excel spreadsheet. The router deals with
Layer 3 and could care less about the higher layer protocols (unless you
have configured ACL's to filter such things).
To rule out the carrier as the problem see If you are able to ping reliably
across the WAN with 1500 byte packets. Then change the bit pattern (using
extended ping) to 0x0000 and 0xFFFF that would test the all ones and all
zero's integrity. Once you do all of that and the pings get through then
you can "probably" rule out the carrier.
Just a thought, but you haven't changed the MTU on any of the interfaces
have you? You want to make sure they are the same on both sides. Also I
would recommend running Fair-queuing on the 64k links. That will aid in the
interactive traffic getting through when there is a large FTP or SMTP mail
with an attachment trying to get out. As far as the queuing on the 2MB
side, FIFO is probably your best bet since there have been a lot of issues
with fair queuing on larger bandwidth links (T1 and above usually).
Sorry I don't have an exact answer for this, but there are a couple of
suggestions on troubleshooting it. For what it's worth, hope it helps.

Could be a carrier issue, try extended ping using various date sizes till
the largest 1500 if you only have ethernet, see what happens, and pls let
use know the result.
Good Luck
