1895 prepped for deer season, boar and Alaska?

I recently traded my High Standard 1911A1 FS w/ammo for a like new Marlin 1895 45-70. The gun is stock w/a 22" blued barrel and 4 shot mag tube. It has a BSA Deerhunter 1.5 scope on it.

I was wondering what I would need to add/change/customize in order to get it in fighting condition for an eventual Alaska trip my friend and I want to take. I'm talking everything from finding a longer mag tube to sling, butt cuff ammo carrier, replacement sights, ammo, etc.

I'd also like to try it out deer hunting here in TN or boar hunting in TX. Any thoughts on ammo and acessories or mods would be greatly appreciated. I LOVE this rifle and realize that there are different variants, barrel lengths, and such but--for now--this model is what I have to work with (unless someone local wants to do some trading).

I took it camping this past weekend and ran a box of shells through it. It beat the **** out of my shoulder but I loved every second of it (I guess I'm a 5'7" 165lbs masochist). I also have an STG-58 FAL clone that I love to shoot so maybe I just like the bruising that goes along with big caliber rifles?

(to be honest, the 45-70 didn't actually bruise my shoulder...but I did cut my nose on the scope with the first shot, which is what happens when you don't get eye relief that properly respects the recoil!)

Thanks for all your help!

PS: I've seen the SBL/STP variants of the 1895 and they look awesome but I don't have the money for them now and have been told that stainless can make aiming difficult in sunlight alongwith alerting your prey to your position.
