Don't worry about the Equipment, the actual DSLR are incredible compared to what we had 6 years ago. I will tell you whatever the price of the equipment, a crappy 4 Mpx pic is a worthy as a crappy 20 Mpx pic, but a beautiful 2 Mpx picture is way better than a lame 22 Mpx pic. The equipment is just a tool to help you achieve certain goals, but it has no value compared to the opportunity and the way you show a certain event. BTW I use a very small Canon SD780IS most of the time especially when flying, and I have some of the most beautiful shots from it.
I hear you, 2009 has been a hard year, happy its ending if you ask me
I personnaly have equal respect for Nikon than for Canon, its just I started with Canon and over the years the investment makes switching brands impossible because of the non-compatibility.
As for your gear, its a nice setup to begin with, just watch out for your lenses because they are telescopic lenses (they vary in length) and this is a fragile design, so whatever you get get something padded I wouldn't try my luck on them.
Seeing the gear you'll be using, maybe the Mongo S-Type Versipack might fulfill you.
