A good thing to do is to find a few tracks that have clear intro/outro's with only a kick or a kick and hi-hat. This will make it easier for your ears to follow what is doing what with regards to tempo of the tracks for beatmatching thus keeping your mix in check if your holding it for a while and stop you getting lost in a sea of pads and percussion. Not sure what style of music your after so don't know how readily available tracks with this type of intro/outro are. Another good way is to just load the same track (when I was learning it would be buy two copies of the same record) on both decks, increase the pitch on one deck to a random % and try to match them up.
