Boots: La Sportiva Glaciers
Packs: Conterra large day pack, Osprey big multi-day pack
+2
Huge HUGE fan of LaSportiva boots. I had a pair of K2 boots for about 9 years. When they wore out I replaced them with another pair of K2's. They are no longer made but pretty much equivalent to the current Glacier's.
I have a bit of a fetish for packs and headlamps. All Petzl on the lamps. Packs I have a mixed bag but for larger packs I really like the Osprey line. My wife, an EMT and SAR member has the Aura 50. I have a Mutant 38 (only available in Europe at the moment - I love knowing the Product Manager at Osprey!) and plan to add a couple of their larger packs.
Also - True North packs are great for SAR 24 hour packs. They are light, fast, and ride well with lots of space that is well organized. They are primarily geared toward Wildland Fire guys but now have a SAR line. I have some of their civilian/sport lumbar packs and love them. I have a friend that has their full-size trauma bag for a jump kit and the thing is huge, compared to my Conterra USAR pack.

Conterra for my medical bag (USAR pack) and Radio Chest Harness (Tool Chest).
Hope that helps. I've got about 16 years of gear that works and doesn't work so if you want more advice before you spend money, just drop me a PM.
