yes, you do need training. ;)
there are a lot of things in your post that are red flags (he acts up - you laugh at him; he tries to "tease" you by taking your shoes/clothes/whatever and then runs away when you try to get them back; he lunges at a passerby and grabs his coat; etc. etc. etc.) you seem to think they're funny, but in truth, that sounds like an obnoxious rude dog to me.
It all comes down to a lack of training - yours - you need to learn how to teach your dog some manners!
You are definitely not giving him TOO much love and attention, but you're not giving him ENOUGH attention in the right direction.

One year old is not too late but get enrolled in some FORMAL obedience classes (don't try to do this on your own with books) as soon as possible. At very minimum, enroll in your local Petsmart or Petco classes, they have six - to eight week sessions that will give you the basics.
