but now I'm whit some troubles about how to mix Modes with pentatonics to make some solos and arrenges to my songs.

You can just think of the modes as the "pentatonic scale with flavor". The natural minor scale (Aeolian) is just the minor pentatonic scale with two notes added, and so is the Dorian scale, Phrygian too for that matter. Just try to listen for what those extra notes add to the scale, what sounds, what feelings. Then you can think of the pentatonic scale as the shell, or frame, and the other notes as spices or little extras :).
