The best thing I can suggest is gather a good number of licks. Once you feel confortable with them, pick up a midi file (instrumental if possible) and try to fit the licks in the song. Try to put them in sequences.

This exercise will help you recongnize and adapt to different beats/scales/key and with time you'll be able to fit your licks in almost any rhythm track.

Just surf around this site for new tricks and make a simple query on the net for midi files. As the others suggested, start out with blues.

This is money friendly solution :)

We all like those ones don't we.
