    My questions are; is a bolt ok without a new carrier? Do the carriers wear out or wear with the bolt that the need to be replaced together or can I just get bolts and be GTG? Are there any other spare parts that would be needed?
    Barring you lose a spring or detent during assembly most things on a LPK are highly unlikely to break. Probably the only things that I would consider a regular wear item out of a LPK is your hammer spring and your safety detent.

    Other than that all you need is a spare bolt(you can cannibalize everything that comes on that bolt that you might need like extractor, extractor spring, gas rings ect.), a spare firing pin, firing pin retaining pin and cam pin.

    I have a complete spare bolt carrier group for each rifle but also have extra cam pins, firing pin retainers, extractor springs and gas rings in my spares box.

    I also have a few lower parts kits on hand but I've never had to rob a part from one of those because of a breakage.

    In my own limited experience with both home and factory built guns, whenever I've had a part wear out or break it's always something in the bolt carrier group.

    Buffer springs are a good thing to have on hand if you ever take a class or plan on doing any kind of volume shooting.

    I keep this kit and a complete bolt, hammer and trigger in a small Plano "tackle box" with my range gear.

    You really don't need a Grip lock washer. That's .73 that you don't need to spend.

    What spare parts to get

    I just keep an extra lower parts kit myself. I have a spare BCG and also have gas rings and other parts for the BCG but I fully assembled spare BCG as well. My BCG is a nitride one which is fine for a backup.
