I'm not too sure if God's Rocket Punch takes place in the Hayate no Gotoku! universe or not, but I can reassure you that Heroes of the Sea Life Savers does since Hata has confirmed it before in the past. As for Sore ga Seiyuu! I'm not too sure where that fits in the timeline, but judging from the first Volume I'd say around late winter/early spring.

As for CAN'T TAKE MY EYES OFF YOU that might have to be labeled as "anime only" because Hata has stated in Volume 34's omake that the events from the series wouldn't be in the manga once it was animated. However, that doesn't mean the events from it won't take place off screen kinda like how the destroyed Motion Picture Research Club from the light novels was referenced in the manga.
