John; IPX is very sensitive to delay variation. That is why you are dropping IPX more than IP. My Novel expert recommends running an NWIP tunnel if you have a novel server on each side. I know. Great. Another tunnel. The large number of differed packets could mean several things. My first WAG would be a broadcast storm. Second would be a routing loop of some type. A packet capture on the link during the problem should tell the tale. My impression is that there is very little to "tweak" on a GRE. Also, it could be a service provider congestion issue. If that is the case, a SLA (service Level Agreement) would be the only effective cure. If the traffic travels through multiple ISP's the SLA becomes more challenging.
