There are a number of things that can be done to tune up your band saw. Mark Duginske has a good book called "Guide to the band saw" or something like that.
While making sure the guides and thrust bearings are properly setup is important for blade tracking, it has little to do with vibration unless you're running the blade where any of the guides are touching without a workpiece being cut.
The guides should only spin when cutting stock. If they're being engaged by just the blade, you've not set enough clearance between the blade and the guides.
The side guides should be set the thickness of a dollar bill away from the blade. The thrust bearing should be set the distance of a dollar bill folded in half twice. Don't forget their are guides below the table as well.
Since you're using a newer band saw, you probably have crowned urethane tires. You probably don't need anything more than a brush to clean those. Some manufacturers install a brush in the lower wheel housing. If not, it is an easy modification and well worth it. Mount a bristle brush to the housing so that it clears the dust from the wheel. Google will give you some good photos. I think Grizzly sells them, among many other suppliers.
Don't forget dust collection as well. It is best done above the table as well as at the lower wheel.
The link belt is useful for vibration.
Besides making sure your band saw is level, also make sure that the wheels are co-planar. Use a large straight edge to see if you can touch both sides of the upper and lower wheels at the same time with the straight edge. If so, the wheels are co-planar. If not, see your manual for adjusting the wheels. Sometimes shims are involved and you may have to remove the table on some band saws.
Check your blade tension as well. If you have a newer model saw, you should be able to flip a lever to release tension when you're not using the saw. This will help the blade last longer, since it isn't constantly under tension.
Another tip is to take a honing stone and smooth out the rear of the blade. This will also extend the life of the blade and make a smoother cut where the weld isn't tearing at the wood.
There are a number of blade cleaners, but a buddy turned me on to good ole' oven cleaner.
Good luck,
