getting new tires
I have a 2005 Trek 3900 with Bontrager Connection Trail, 26x2.0 tires, and Alloy front, Shimano RM30 rear hub; Matrix 550 rims. Is it possible to go to my LBS and get new and better tires that are maybe 26x2.3 - 26-2.5? Or is that just not possible. And if I can, would I have to get new rims and tubes?
Probably the deciding factor will be the clearance in your frame and fork, not your rims. I would venture to guess that 26x2.5 is out of the question on the rear if that is an XC type bike(maybe not). You may be able to get by with 26x2.3.

Other things to think about:
Fatter tires are going to weigh more(maybe significantly more). Adding rotating mass, espescially far from the axle, is absolutely the worst place to add weight to a bike. rotating mass effects acceleration... not to mention having to haul the extra weight(possibly significant extra weight) up the hills. Fatter tires will tend to increase rolling resistance (larger contact patch), though, tread design is also a major factor here.
Fatter tires will tend to float better in soft trail conditions (like sand) and can yield very good control characteristics(climbing, braking, cornering) due to the fact that you can usually run lower air pressure.

ride hard take risks
For your age & size i would suggest Maxxis HighRoller 2.35 front & rear.
