Hello Mikechello, welcome to the forums. is this a new bike or just a new to me bike? if a new to me bike get the shop to show you what to look for.
one thing that is good to do, get inthe habit of wiping it down once a week and look everything over. then when something is wrong you will notice it. that way when you wipe down the rims and spoke you can feel loose spokes and look for wear and cuts on the tires. see if the wheel wobble would indicate a loose hub
PS this site (not mine) is chock full of good information from a lifetime of being around bikes.
