Hi RH, welcome to the great outdoors! You guys are about to really be smitten, if you think dayhiking is great from a photographic perspective. Just wait until your first morning just before dawn in the woods, or when a fog rolls in, or ... there is no light like that you find in the backcountry!
Anyway, on the gear front, the gear you've selected certainly seems to be of high quality. I would take a look at your sleeping bags, are they down or synthetic? Most users here prefer a high-quality down bag from makers like Western Mountaineering, Marmot, Montbell etc. Down bags are lighter, more compressible, and have much greater service life than synthetics. I've also never found a synthetic bag that lived up to it's rating, while the down bags I've used always seem at least spot-on if not conservative at their rated temp. Don't worry about getting down wet; in all my years of backpacking in the SE, I've never gotten my bag more than lightly damp. Those instances were always under a minimalist tarp, whereas you will be in a tent.
You might also look at the Precip rainwear. It failed in severe rain in my usage, and I know a few other members have experienced this as well. The pants are fine, but I would look for a more weatherproof jacket. Good choices at a similar weight might be the Montbell Outpace (uses BreezeDryTec, one of the most respected of the WB materials frequently used by members here) or any jacket in Gore Paclite like the Golite Phantasm. Or if you want the pinnacle of performance, get an eVent jacket.
Have a great time! When you really get the bug, come back and see us for ways to shrink those pack weights; every 1.5 pounds or so of pack weight you lose equals another piece of glass you could carry! Lose 3 pounds and you could carry a big tele for shooting birds and distant wildlife!
