hey, welcome to the camaro world. I think you would be proud to know the v6 3rdgens are some of the best handling camaros. the lighter v6 makes them balanced. I think you would really enjoy some autoX events with that car. If you do, install a wonderbar, and uprgrade the swaybars (easily found at your local junkyard). Two cheap and easy mods.
Any way your questions,
1.Yes that is a 82-84 z28 hood. if its fiberglass its somewhat rare.
2. Crack dashes in thirdgens are as common as t-tops. either get a dashmat or find a new one at hawksthirdgenparts.com or thirdgenranch.com
3.Main color does look like a stock color. there are several blues for the thirdgen like that.
4.Here is a link to a refubished cluster

6.as somebody already said Inflatable Restraint, check the fuse and you can check the the connection inside the steering wheel.
7. 1st thing to check the steering is to drive the car onto ramps and have somebody turn the wheels back and forth slightly and see what in the steering linkage and ball joints is loose. Everything should be tight and move smoothly in one piece. with 168k on the clock it would be worth your money to replace the ball joints, inner and outter tie rods, idler arm and center link all at once and then you can forget about it for years to come. Use moog parts.
You may also have a steering gearbox issue. here is a link to adjust it or rebuild it
http://www.thirdgen.org/techboard/su...build-rag.html Check out post 32, it covers the ratios.
http://www.thirdgen.org/techboard/su...g-gearbox.html . Or you can replace it but pay close attention to the ratio. Most parts stores don't keep track of the gearbox ratio so you could have a fast ratio and get a new one with a slow ratio.
good luck! Keep it simple with the engine mods, unless you go turbo but heres a link. make sure you read the stickies
http://www.thirdgen.org/techboard/v6/ . It will be a killer autoX car once you get the steering fixed, add a wonder bar (don't autoX without one) and upgrade the sway bars. heres a link to help with suspension with some info on stock swaybar options
