Plastic pcb standoffs are the best thing to use in my opinion. You have to make small holes in the board for them to fit though, so if you don’t have room you can use small plastic spacers as well.

Your audio jacks are fine. You don't need the enclosed box-type ones.
In case somebody else didn't mention it, try covering the inside of the cover in electrical tape.
Also I haven't tried them yet, but I'm going to try some sticker-backed PCB standoffs on my next build: https://www.amazon.com/gp/product/B01LDLTNAC/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1
I'm very accustomed to using regular pcb standoffs, but those require you to drill a hole through and secure it with a screw. These use double-sided sticky tape to the enclosure, and tension on the pcb.
