First take a deep breath. It is not likely that the Magesterial District Justice will set a monetary bail for you for such a small offense. Its not a guarantee but I don't think its likely. Frankely I think your $500 would be better spent on hiring counsel to advise you and represent you. If you can't afford counsel go to the public defenders office ASAP. To answer your initial question more directly, yes you can pay bail a the District Court office right after the hearing.

Whether monetary, secured bail will be set depends on various factors. If you've been charged with a felony retail theft and the items were only worth $33, then you've obviously got a bit of a criminal record. Generally, unless you've got a history of failing to appear in court or a particularly zealous MDJ, you are likely to get unsecured bail, meaning you won't have to pay anything now, but will if you fail to show up in the future.
If things go badly and a bondsman is required you can ask for a list from the MDJ. Most have that information on hand. There will not be a bondsman right at the MDJ's office.
I believe this is a repeat question. Again, it is entirely possible to get charges adjusted at the preliminary hearing, but you're going to need the assistance of an attorney to help with this. As before, I do handle cases in York County and would be willing to represent your husband.
This answer does not constitute legal advice and does not establish an attorney-client relationship.
Retain a private criminal defense attorney for the preliminary hearing on Thursday. Good luck.
