You'll have to buy special bulbs that are built to function with the ballast still in - those kind of bulbs will only be available on more common fixtures. Depends on which florescent tubes you mean to replace.
If they are available, you should be able to save a little energy, but not as much as the "replace ballast ones", and the cost will be 1.5x-2x more than the "replace ballast" LED bulb. 1000bulbs.com is a good place to start to see if a "direct plug and play" bulb is available for your specific tube type.
Still, I would recommend giving the replace ballast thing a shot, even if you've never done it before! Watch a video or two on youtube - the first one might take you 45 minutes plus a trip to the hardware store, but after you figure it out you can rewire a fixture in 5-10 minutes.
