Thx Paul.  Yes the asbestos is out.  It was held down with small tacks in each corner and on a couple places a small dab of glue.  I moisten it slightly with water to keep it from dusting and was able to pry it out (wearing a good respirator and gloves).  The glued parts I moistened some more and the glue dissolved and the mush came up in a paper towel.f  All into a sealed plastic bag and then I wiped down the inside of the cabinet. 

The warp on the worst side is seen below.  Its not terrible but it is more than I wanted to just try and snug up with a clamp and glue.

Looking around for "fix warped wood" on youtube I came across this video (by "fromthewoodshop") which is the technique I used on both sides of the cabinet.  Heated from the inside with a heat gun for 3 minutes and then let cool.  The sides did pull in some so I went ahead an forced glue down the cracks and sides and clamped it.  We'll see how it turns out and holds up.
