I have problems with my hands also,not shaking like you but I have difficulties holding things.
You could try enable scaling and work from left to right,0 being the initial input. You can lower the sliders and work your way up in a stair step or parabolic curve.
I would think though that by increasing dampening and adding some deadpan you could solve the problem you have with just those 2 sliders and not need to enable scaling,or use it also the choice is yours.
Deadpan will increase the size of the centering of your stick,think of it like a dime as you add more it grows to a quarter and then a half dollar,ETC. This will allow you to find center easier,then add some dampening so the movements aren't to jerky and I think you should be able to resolve your problems.
I'm usually in the TA between 9pm and 11 pm est, I wont be on tonight but hope to be on tomorrow,if you look me up I'm sure I can help you smoothen out the responses of your controller.
I often find player who've been around for years and even they could use some help sorting out their JS...... Ya Joe I'm talking about you!!
If you search back in help and training you should find numerous pix of others scaling settings,could try hardware and software section also.
