I want to buy my first home in the next 3-5 yrs. How high should my FICO score be?

I really want to buy a home before my kids get too old. I have 2 and 1 on the way. I am in no shape to buy right now so I gave myself 3-5 yrs to get a better paying, more secure job and to build my credit score to the best that it can be, but I don't quite know how to do that. My credit is currently poor and I don't know how long it takes to bring it up 200-300 more points. I'm hesitant about buying w/ my husband because he has long term child support obligations which lowers his income quite a bit and his credit is bad too. How much should my income be if I don't want to get in over my head. I really would like to own a nice home for my kids and have something I can pass on to them, but I don't have a clue about where I should start. PLEASE HELP!!
