Well, it can be a battle, and it's also a commitment, so make sure you know what you're getting into.
In my area of Virginia, we either have to limp a cool season grass (like Fescue) through the summer heat, or plant a warm season grass (like Bermuda) and accept that it will be dormant and brown from October-April. I planted fescue. My chief issue is irrigation, followed second by fungus/mold due to humidity. The rest comes down to having good soil, aerating at least once a year, and using fertilizer and weed killer as needed (I try to use as little as possible). It took about 6 years for my lawn to really establish itself, but it looks great now.
I said all that to make the point that you will want to get information/data on what needs to be properly fixed, corrected, and setup in order to get your grass crop to grow. Under the right conditions, most lawn grasses will thrive without too much trouble. It's setting up those right conditions where all the work comes in!!
As far as fertilizers, I use whatever is a fair deal when I am shopping around. I have used the Scott's stuff with very good results. They do tend to make it easier to understand, and I think their website can give you the proper program for your area and type of grass.
