As far as getting your emails back, you're out of luck. The 5 days that you got is based on a setting on the BES that the admins control. Emails only populate back to what they've set on the BES. The only way to get everything is to restore from backup and then Enterprise Activate.
As for the BB being too slippery, I suggest this:
BlackBerry 8800 Full Body Shield
I put one on my Pearl back in September when it was brand new. They come with a lifetime guarantee. Mine finally started looking kind of worn so I sent it back to them and they sent me a new one. When I took the old one off the Pearl still looks brand new after 8 months.
