To go along with Bob's info here's a link to a picture by picture, step by step on changing out the spring and doing some basic polishing to the action parts. The polishing should be done on the very finest sharpening stone. This would be something like a fine arkansa stone. If it's a brown looking india stone then it's too coarse to leave a nice finish. Another option for a polishing tool is some 800 grit wet or dry sandpaper backed up on a nice block of known flat aluminiun or steel. Use some mineral spirits as the lubricant for the sandpaper.

If all that looks like Greek hyroglyphics to you and you think the $200 to get the nice trigger job is worth it then go for it. But if you just do the springs you'll get around 80% of the same feel over all.
