What you're saying is very normal, we have all been there and it will get better! This is a key time in deciding how you will parent though. There are so many different approaches but the one I have gotten the most out of is Love and Logic. It is a great book to buy, I keep going back to mine time and time again. http://www.amazon.com/Love-Logic-Magic-Early-Childhood/dp...
Another great series of books to help you figure out what to expect at each age are the books written by Louise Bates Ames, they are by age
http://www.amazon.com/Your-Two-Year-Old-Louise-Bates-Ames...
These you can usually buy cheap at a Half Priced Books, if you have them in your area.
For bedtime plans, and other obstacles of toddlerhood I love the Baby Whisperer Solves your Problems
http://www.amazon.com/Baby-Whisperer-Solves-Your-Problems...
Its best to go to a book store and start reading the back of these types of books to see what style will work best with how you would like to parent. I could tell you what I do, but with kids, it really takes several different approaches as your child will get wise to your ways and you will many times have to figure out some creative parenting to get your way. I do highly recommend the Love and Logic book as a start. It has a great foundation and can grow with you as your child grows.
Good Luck!
