You have a few options depending on the look, durability, and how much work you want to put into this. If you use a latex floor paint - the easiest option - many of those products are self priming and acid etching isn't necessary in most cases. A good cleaning, powerwashing if possible, would be best. Most importantly, you want to make sure the floor is completely dry before painting. If you powerwash, I would wait a couple of days before even thinking about painting. A simple moisture test will tell you if the moisture content of the cement is too high - simply duct tape a piece of plastic about 2' square onto the floor. Let it sit overnight and the next day peel it off. If moisture/condensation builds up on the underside of the plastic the floor is still too wet.
If you decide to use an epoxy - more durable than the regular floor paint - than acid etching in most cases is necessary. Same procedures apply for cleaning and moisture testing. Stick to a waterborne epoxy as it will be much easier for you to use and have a longer pot life (working time). You could also look at other products like Roller Rock and spread rock if you want a little design - these are made by Daisch coatings and will give you a more decorative finish. Whatever you use, I would read the product directions and be sure to follow them - the specific product will tell you if acid etching is necessary and what prep steps to take.
Good luck!
