I agree with what's written above. Here are some other random thoughts:
A roommate is an excellent idea, because you'll be getting everything for half-price. As above, it is imperative that you have similar lifestyles and habits. I would also only room with someone that I knew previously; I know that (unfortunately) from experience.
Bundle internet and basic cable. Don't waste money on HBO/Cinemax/Showtime or Directv unless you have a roommate to split the cost.
An "all-inclusive" deal for rent and utilities sounds like a good deal, but I usually found that this sort of setup is only offered by apartments that are of relatively-low quality. It's probably better to just find a decent place and then be responsible with the utilities.
You can often find a better deal by scouring craigslist and the classifieds for properties that are being rented by individual owner/investors than simply going with the local large apartment complexes.
The ultimate goal is to buy a property (home or condo). I'd focus on finding an apartment that's convenient, safe, and clean for a reasonable price rather than spending big $ on rent for a flashy condo, even if it seems like you can afford it.
Try to find a place with a washer/dryer, even if it's one of the small apartment models....this will save you an incredible amount of aggravation.
If you anticipate buying a home/condo soon, make sure that you have some flexibility in terminating your lease, i.e. don't allow yourself to be placed on the hook for several months' rent or in the position of having to find someone to sublet your place.
When you move in, you will be given a walkthrough sheet to document any preexisting damage. Be VERY picky with this, write down everything even if it seems minor. This way, you can be sure of getting back your security deposit when you leave, provided you haven't trashed the place
You can probably get most of your furniture from friends and family....most people have a decent couch or table/chairs that they'd be happy to donate to your cause...don't waste any money on nice furniture right away; you'll probably move a couple of times before you settle down for good, and anything nice will definitely get damaged during those moves.
Definitely make a budget, especially for the first year. Like the poster above said, it can be more expensive than you realize, especially at first. Planning out your expenses in advance not only prevents you from running out of money, but also allows you to establish a regular savings/investment plan once you know how much disposable income you truly have. Be cautious about impulse buys and eating out, especially casual things like a daily Starbucks caramel macchiato...
That's about all I can think of for now...maybe I'll think of more later.
This is an exciting time...it's a great feeling to finally be master of your domain, even if it's only a one bedroom apt.
