I finally got home to open 5105, and now that I've got it it just makes sense... Trouble is I have to wait for my Birger mount and Pro LCD to actually fire it up and start shooting.
In addition to the standard fare I bought a second top mount and handle extension. After seeing how it goes on I'm glad I did. The stresses in the camera body without this could eventually break the body resulting in a dropped camera - not good. These should be delivered in the base production pack IMHO. As a secondary benefit the second top mount at the rear of the camera is an ideal place to mount cable management / stress relief tabs.
I found out to my dismay that the Red Case does not have a cutout or room for the handle. If you are considering a Red case you should take this into account. The rest of the case is well thought out, and I'll probably copy a lot of the things they did.
I also bought 3 16GB CF cards and a battery belt clip. My intension is to affix the battery belt clip to a tripod leg and not run the batt/drive cradle. This will substantially lighten the load on the tripod head and make camera movements easier.
Now all I need to do is think of a clever name...
