Questions regarding Ushers?

With that many people, I would consider the sweetheart table vs the king's table. I am not sure if you can find one that big, and you can break up the wedding party into two different tables with their SO's and plus ones.

Ushers are not really considered part of the wedding party in the traditional sense, but I personally would consider them as such since have to wear a specific outfit and they have a working role in the wedding. It's not really an honored position, but by including them you can make them feel that way. If these are the combined wedding party photos, I think it is polite to include them. If you are taking the combined photos prior, I am wondering what the difference in photos would be that you wouldn't have already captured.

What's one extra photo so everyone is included? I guess I am missing the problem, will it really take that much more time? It's 4 people who just need to pop in, smile, and then you leave. You don't have to take multiple shots in different poses. You could also take photos at the reception venue as well. It's your call, and it's not wrong which ever way you go. If you can, it's just an extra measure to show you value them. If they have to attend the rehearsal, they get invited to the dinner. To me it's more about not making them feel less than because they are not groomsmen

With that many people to potentially seat at a head/ king's table, I'd probably opt for a sweetheart table instead. Unless you're having a large number of guests, you'll wind up with the bulk of people at one table and it might make people feel awkward if they're at one of the few other tables. My mom really tried to sell me on a head table, but once she saw how the tables worked out with the sweetheart table she actually came around to the idea.

I would not include ushers at the head table personally. I've never been to a wedding where that was the case. They may have sat at a table with each other, or other mutual friends, but not at the head table.
