The bolt running through the stock is for recoil reinforcement. It is not ever necessary to remove them. If you look at high end big bores they are usually flush with the stock and have no facility to remove them. Glass bedding is not hard but I would suggest watching a number of videos on the subject. The key to not screwing it up is attention to detail. There are a lot of tricks you can pick up. For instance, lamp shade rod makes great custom pillars. For a release agent the best I have found is Kiwi neutral shoe polish. The best bedding compound I have used is Devcon 10110 steel putty. All of them work but Devcon 10110 shrinks less than others like Acraglass. Taping properly is critical and buy the pointed q-tips, they get the bead of compound out of the seam between the action and the stock really well with less mess. Plumbers putty is truly your friend. The only other thing I would say is, glass bedding is not hard but it is not what I would consider a beginner project.
