For the store, enter one of the clubs through the portals in the club building in the Hub and try opening the store again (had this same problem with the Going Green testing -- pretty sure it's a limitation of the PTS). For the fishing pole, this happens on live for me too (guessing it's happening more on PTS due to lag), but you can also swap classes to fix it (not much faster) -- seems to happen when the line is recast before the "bobber" completely disappears (mostly happens to me if I don't reel in quickly enough after the bobber starts jumping)
I went to hub and all of the club portals were "out of order" for me. I tried changing worlds and going into and out of the club I am in..no store. I will try a few more things in a minute.
I tried both quest givers again today at the beginning of U8 and neither satisfied the requirement to "complete a Geode Topside Adventure".
The fishing pole thing is more common on PTS, I wanted to report it just incase they somehow broke the pole again while coding the new content.
