The tikka is a fabulas action, more refined than the 700, but the 700 is a solid work horse. I would reccomend the 700, as there is more options later on down the road, and they have an after market that's large enough to choke a small child.
My only point to really pass out is to get a rifle that can change as you get better and better if your on a budget.
The krieger barrel is a great choice, but don't forget about benchmark. Great quality from there. If your on a budget, it would be a wise choice, but the barrels not something to skimp on. 1-10" 5 is optimal to me.
As for the stock, I'm really one sidded, so take it with a grain of salt. Look at your needs, and pick one from there. I say you can never go wrong with a hs precision, or mcmillan.
Hope you have a blast!
