Does the Mail SPF actually do anything? Should it be checked or not?
It should help prevent spam once more providers start utlilizing it,its worth it to be on,IMO.

But will hurt things to have it on if is not using it yet?
Nope,doesn’t hurt at all.
What prefix value do you recommend we use with SPF? The default prefix value is ‘pass’.
fail: the mail is a forgery, and you can reject it with confidence.
softfail: the message could be a forgery.
pass: the mail is not forged, but that doesn’t mean it’s legitimate.
neutral: The domain owner has explicitly stated that doesn’t know whether the IP is authorized or not.
If SPF stops SPAM, shouldn’t it be set to ‘fail’?
