Eh? Maybe try reading the caption of your posting. The GS might say something about model or make but serial number usually covers date, place, and order off an assembly line somewhere, if that much.

Those are ball bearings. If they are out of the wheel you have a complex problem and repair. I suggest you take the wheel to your local bike shop.

the gear that needs to be replaced requires a special tool. You can get one online whereever you buy the gear you should also be able to purchase a splined socket to assist in getting the old one off of the hub. Might I suggest ebay.com?

The silver washer will go between the frame of the bike and the peg. Then the nut for the wheel bolt will go into the peg and screw on from the inside of the peg. Unless they are solid pegs in which case you will put the washer on first still and then screw the peg on as if it were the nut itself.

you can drill holes in the handlebars through the center piece, or chop off part of the seat post that isn't being used and drill holes in the seatpost where it is used. other than that buying lighter parts is the only way to go

Take it to a bike shop, you are dealing with a trick bike. You do not want to have the brakes fail from a bad adjustment, unless you have the right tools and know how, because you are having to deal with the spacing on the detangler and it takes skill to do it right, do not do it yourself. Someone can get hurt in a diy.
