Laura, I suggest you burn all of your gig CD's as CD-Audio (so max 10-15 files on a single CD). Regarding compatibility issues (I assume that was your question?) it is not important in what digital format the source files were (wav, mp3, flac,.....) from which you created those audio CD's. Just burn them at low speed (like 4x) and use quality blank cd's.
Some CDJ-1000's do read the digital format files (only mp3) but since you do not know what mk version the club has it would be ill-advised to burn your mp3's as data cd. Wav files (burned to a CD as data) are not supported in any CDJ-1000 versions.
