It's always helpful to ask yourself "Will this get me closer to my goal?"
What's your goal in having him served at work - to humiliate him? If that's not your plan, why do it that way? Why not just inform him you have filed and he will be served, he can pick up the papers if he wants. Or you could save money by serving him yourself, I bet.
As for his mom - what's your goal in telling her about the affair? If you're looking for her to be on "your side" - truth is, it seldom happens with family - usually blood is thicker than water. If she's fragile, telling her what a jerk her son has turned out to be will only stress her more.
As for the filing again - ask your attorney whether you can take your half of any joint accounts and move them. You don't want the hassle of your H emptying the bank accounts.
