Love and Logic is great, but the book isn't much help for toddlers (really, there's no help for toddlers -- it's just going to be awful til he's about 4 -- but I don't want to discourage you...). We took a love & logic class for early childhood and that was really helpful.
I've heard great things about happiest toddler on the block, and the principles are basically the same as love & logic, but presented in a way that I think parents can grasp more easily.
In fact, a lot of good parenting books are based on the same principle as love and logic:
clear, simple instruction; firm boundaries and consequences (not firm punishment, but firm as in consistent responses); and don't waste to omuch of your breath -- talking is pointless.
Just know that having these skills doesn't mean your kid won't throw fits or embarass you in public. That will still happen -- it's the nature of a toddler or preschooler. It just means you will have some good tools and skills for how you respond to those inevitable situations.
