Thru iTunes you just click the playlist you want, check all the songs you want to burn and the click burn on the top right of the iTunes window (right next to the search field).

Watch out though because the files being mp3s doesn't mean that iTunes will necessarily burn them into that file format; in fact, by default iTunes burns CD's that will be playable on any CD player. You can of course change this by selecting the file format you want the songs to be burned in thru the iTunes Preferences.
