how important is it really to change my passwords?

Crucial. You had a bunch of trojans there.

Are these things I had really going to steal them?

They possibly did already.

Any current issues?

How likely are they to actually use my passwords/log into my bank account etc?
Nope no issues right now! Thanks for the help!

Check your bank statements, call your bank about any suspicious activities.

Good luck and stay safe
