Experienced guitarists?

Question:How do I go about adding the more obscure scales to my resevoir of knowledge?
How do I add say the lydian scale or the ionian scale into my normal improvisation?
How do I know what chords go along with each scale? Are they only chords that include the notes in the scale?
Any information on how to practice more scales and include them into my normal guitar playing would be appreciated. I've been playing for years but never had lessons or learned the proper way to play.
Thanks

i don't know what you mean about obscure, but i guess you mean the phrygian mode and harmonic scales. if so, you just have to play. you can try listening to artists that play on them.
ex: Phrygian: yngwie malmsteen(almost all songs are in phrygian or harmonic minor)
Harmonic minor: Flamenco (Paco de lucia)
Lydian: Joe Satriani - flying in a blue dream
and well, to play on a lydian mode you just have to make a lydian harmony. Ex: A - B/A(that would be on A lydian)
The chords usually have all the notes on the scale so you can play anything you want while all the notes are on the scale or a scale that can be apply-able for the chord progression. for example in an Am progression you can use chords from the aeolian mode, harmonic and melodic minor scales, and you can add the blue note as well(4aug).
In other cases chords are formed from notes that are not on the scale, for example in blues you have all chords turned into 79 or 7 so they are all dominant chords.
last thing, do your songs in different modes and try using every one except locrian which is a little difficult to use. at first you will find some problem to establish the tonic on modes like dorian or lydian but don't give up. the easiest way is to play the 4 and 5 grade of the major tonality with a bass on the note you want to be the tonic: Ex for A
Dorian: A/C - A/D
Phrygian: A/A# - A/C
Lydian: A - A/B
Mixolydian: A7 will do
Hope it helps

There is a good book with just what you're looking for (SEE link below) It comes with a CD with samples of the modes and their chords.
