Some silly TV show is just a sidebar that he was hired to do, and you can be sure they are not paying him what Hedwig could and would.
I don't think that it is necessarily accurate to characterize his upcoming series as a "silly TV show" that "is just a sidebar that he was hired to do." The silly TV show might end up being spot-on, actually, but that would be more a matter of taste, not a statement about the relative value of the show to the network that is airing it and that he has contracted with to do it.
The show has been billed from the start as a variety show. (See here, for instance, where a comparison is drawn to Saturday Night Live: http://variety.com/2014/tv/news/neil-patrick-harris-variety-show-oscars-1201340400/) Many of the elements it will reportedly contain would require a significant amount of work to get it ready to air. I suppose the question of how much of NPH's time that would take up depends on just how involved he will be in the process of generating ideas, writing, and shaping the show to put his personal stamp on it. The mere fact that a show airs live for one hour a week doesn't say anything about how much time and effort is required during a full week to put it together for airing.
That said, it is only going to have 10 episodes this coming television season with a premiere date of September 15. That means it would most likely be done around the end of November. If he is, in fact, interested in another go at filling Hedwig's heels, he might be able to do a run starting in December if they have someone else to take over for a short time after Taye finishes. Or, as you suggest, he might be able to do both the TV show and Hedwig simultaneously if his involvement with the TV show is just to appear on Tuesday nights and do what others have prepared for him to do and say (and, almost certainly, sing).
I do not know what his Hedwig salary would be. I do know that in his last TV series he was being paid $225,000 per episode in 2013-2014. With his name recognition, his resume, his years of starring on hit shows, and his history of awards and award nominations, it is nearly certain he would command at least that much per episode of the new television series and it is quite likely he'd be making significantly more than that since he will be the sole headlining star of the TV show with his name being the major draw to bring viewers to the screen.
