A single stage trigger is typically what came with the rifle...all the finger press weight builds until it reaches it's break point...about 6-8 lbs. This is fine for 99% of shooters that would not benefit from the feel of a two stage (I know I am going to get flamed for that but it's my opinion)
What some do not like is that the break point is reached without any indication or feedback. Again that's fine for average shooters plinking at the range but more experienced or longer range shooters like to have feedback and control so they can sync their breathing, etc with the trigger break.
With a two stage trigger, the first stage is loaded up much like a traditional one stage, the difference is that it reaches a second point in the trigger press before the break. There is a noticable tactile feedback to the shooter and a more predictable final breakpoint.
A good two stage trigger will set you back several hundred $, a good one stage can be had for about half that cost. There are also several vendors that market battle triggers or enhanced single stage triggers that smooth out the grittyness without reducing the pull weight or mass of the trigger or sear.
As for the bolt...different bolts will have little or no effect on accuracy but recoil management, cycling and reliability are key concerns. The lighter or heavier the bolt, the faster or slower it will cycle. Too low a cycle rate and you may see in-battery failure, fail-to-feed, etc. Too high a cycle rate you may get torn casing rims, jams, recoil shock, etc. Keep an eye on your brass...if its falling at your feet there's too little action...if it's landing in the next county there's too much. A neat little pile at 3-4 o'clock, 4-5 feet away should suffice.
