Your shifting issue is caused by the t-case drop lowering the transmission so its shift lever is more restricted where it passes through the shifter boot. You can't remove the t-case drop without causing drivetrain vibrations.
To cure the shifting issue, you can either install a SYE kit and CV driveshaft so you can get rid of the t-case drop, or move the console back a half-inch or so. That is easily done by just removing its self-tapping screws and moving it back, then drilling new holes for the self-tapping screws.
The rattle is probably caused by the transfer case shifter mechanism being a little out of kilter since you lowered the transmission/transfer case assembly with the t-case drop. The t-case shifter mechanism is mounted onto the transfer case on one side and the tub on the other. Dropping the t-case tilts the mechanism which can not only cause it to rattle but to not shift as well as well.
