Our Bassitt really doesn't love her crate either. When we first brought her home, she'd scream for hours (when I left her to go to work). In desperation, we did a combination of 'really really tire her out' (i.e. I get up at 5 in order to walk her long enough to make her sleepy) and 'fool her into thinking she's not crated'. We bought a very tall metal gate with vertical bars (nothing for her to climb) The gate's adjustable, so an area of the hallway has become 'baby jail'. She's pretty happy to go in there, because it's not so restrictive. We still crate her sometimes (for example, we start the night out with her in the crate, but within a few hours she's lonesome and needs to come into bed with me…spoiled!) and when she's in the car, but because she doesn't associate it with 'mom leaving' she doesn't hate it as much.
The secret for us was to do a bit at a time. (put her in baby jail, as soon as she stopped making noise, let her out. After a little while, put her in again, same thing) Exposing her a bit at a time seemed to help.
Good luck! I know your frustration.
(Can't help at all with the chewing. Bassitt hates toys, all she wants to chew are ipod chargers)
