adding bullets to help organize my sidebar

Can someoone please help me to figure out how to add bullet dots next to my category lists on my sidebar.
I’m using a modified classic theme and I can’t figure out what to add to my css file to make this happen.

I also don’t like how my sidebar items are all changed to lower case even though the items in their were originally written with some upper case.

Any help would be appreciated.

Thanks,
Prem
