I've used the Testors decal system and it is recommended. They also include a small spray bomb. You should be able to use any clear coat but don't spray it on too thick or the decal colors will run. Also, don't use a brush to coat the decals as they will smear.

You will definitely need a bonding spray. I have used the Testors system to now but I understand that you can use any good acrylic clear coat. I've not tried any so can't make any recommendations on that.
