MrP,
Since you have weekend hunted over the past few years and have only added the 7-08 and outgrew the camo then i would say all you need is new camo and some 7-08 shells.
Sight it in and go hunting.
Of course i'm assuming that since you hunted the last three years you have a lot of the essentials as far as flashlight, rope, knife, cleaning gloves, backpack etc.
It might be better if yiou list what you have and we can add to it.
