im wondering what you would do to accurize a mosin and how to do it.
floating vs bedding barrel.
glass bedding vs copper chims
after market triggers, do they help at all?

Well, I've noticed after installing jmeck's scope mount that it actually raises the barrel up out of the stock just a hair and basically free floats it without the need to sand anything away, which is cool.
Well, you can shim the receiver. Use some old pop cans or whatever, and cut some shims out to fit in where the action sits.
You can also sand out the barrel channel of your stock if there are any pressure points. Slide a piece of paper between the barrel and the stock and see if the paper gets caught up on any high spots. You'll have to remove the barrel bands and hand guard. If it does get caught up, that's a pressure point on the barrel. Take a socket that will fit in there, and some 120 grit sandpaper and sand, then check it. Keep checking and sanding accordingly until the paper will slide from the end of the stock to the rear sight without catching on anything.
You can also cork the barrel. This works well with the sanding of the barrel channel. For this procedure you'll need a thin piece of cork, or gasket making material. Cut to fit right between the barrel and the nose cap of the stock. It will create a slight bit of upward pressure on the barrel. This may help improve your accuracy too.
These are certainly some do it yourself options before spending lots of money on it if you don't need to.

You could try bending the sear spring a little bit, or shim it with a couple pieces of aluminum can. But too much can make it unsafe. You can always try some fine grit sandpaper, and then polishing the contact points on the cocking knob and sear. But too much and then it becomes unsafe. Definitely try a drop test to see if it trips the sear and cocking knob if you do any polishing of the parts. Of course, it would be modified at your own risk.

The Colonel makes good points. You can also buy a slack spring for about $10 and install it on the trigger pivot pin. It does wonder for reducing the take-up of the Mosin's two-stage trigger so it breaks more crisply.
A Timiny trigger is wonderful, but as noted it costs as much as another Mosin Nagant.
Free-floating the barrel is not hard to do. The 'piece of paper' that I've found works best for the purpose of testing for high spots is a crisp dollar bill. At my gun club, Louis the Mosin Kahuna swears by the rubber silicon caulk used in making sinks and batutbs watertight. You just spread some into the barrel groove and then reassemble the rifle. He says the rubber damps out the vibration caused by firing and levels out the barrel channel. The rubber caulking compound also has the virtue that if you decide you don't like it and would rather try something else, it peels out easily.

If you have a 91/30 you might want to look into pressure bedding the barrel, if you are talking about a carbine then free floating might be a better idea. Stoning and polishing the trigger is something that you should only do if you know what you are doing BEFORE you start.
i polished the trigger and it helped but the slack is still there. i have been told about useing a ink pen spring to take out the slack. how do i go about doing this,where do i place the spring?

k-80, go back up the thread and read what I said about the slack spring. You can pick them up on eBay for about $10. Installation is simple. Follow the directions, which boil down to this:
1. Remove action from stock.
2. Remove bolt from receiver.
3. Using a drift punch, drive trigger pivot pin partway out of its holes.
4. Insert slack spring into the space between the pivot pin holes.
5. Drive pivot pin back through slack spring into second hole. (This is harder than it looks.)
6. Reassemble rifle.
It will probably take you about 15 minutes, ten of which will be you swearing at the pivot pin as you attempt to reseat it. However, the reduction in the tacke-up of the trigger is worth the effort.
Hahah, Thx Capt. There are quite a few very low budget options (and by low budget I mean zero budget) since they are all pretty much something you can do at home with tools at home. Let us know how it turns out!
