Pretty sure that Praveen's axing was something to do with something he said or did in the domestic game? His temperament, or that's what I heard. As for Ishant... I posted something on cricinfo but my iphone decided it didn't want to let me. Basically, Ishant has become somewhat complacent in the Indian side, because of (in his view) a lack of seam bowling, so he must feel comfortable in the view that he won't get dropped (or if he does, he's next cab on the rank). However, I sympathise in that what poor person would want to run in off 30 yards, for 20 overs a day, on a track with no seam/swing/(variable) bounce, when they can walk in off 5 paces and get turn from the outset? The tracks in India are woeful and they complain about a lack of seam bowling depth. I wonder why...
Also, on the topic of Ishant going to County Cricket à la Zaheer, he's not fit to lace Zaheer's boots. Zaheer got in because he was very good, and worth having as an O/S pro. Ishant would want too much money (because he's an international) for someone of his calibre, unless he finds his form that he had in his earlier days, he's barely worth a spot in a County 2nds side.
