I can't find charms anywhere in the various menus.  I also can't find where my loyalty points are shown.  Is the treasure chest icon in the bottom task bar considered the Clan Store?  Because if not, then I also don't know where the Clan Store is.  When I opened the game this morning, there was a window that showed three or four buildings that I could make; one was a workshop but don't remember what the others were; in any event, I can't remember what I was doing when the window came up and I can't find it now.  I made a clan so that I could do things that I can't do as just a random Jarl, so people are joining my clan that are even newer than I am, so most likely no help there.  I like the game, but the UI could use some work.  All I can do is upgrade buildings, train troops and go into the building that has the nodes to fight things and collect coffers and stars.  I'm only level 42 and Baggi is only level 10, so with the problems I've mentioned, I just don't know how to proceed. 

I should have mentioned that I'm only a few days in and while I like the game so far, I'm having a hard time seeing a long future playing if I can't resolve some of the aforementioned issues :(

If you have only been playing a few days, then you have done pretty well to get to level 42 and 10, though to be fair, the start is much easier than it used to be, especially if  the equipment of the north items are purchased.

If you are finding it tough now, just wait till you get your head round things, especially, if those who joined your clan start asking for help, but dont worry too much, most will drop out when they realise the costs of continuing.

The treasure chest is not the clan store, its open to all players to buy its contents. 

Someone else (if not you,) asked about charms, just recently,(I just checked,it was you!! read about them in that thread. 

Just click on everything that opens,you will soon get to know where things are, the menu icon lists loads of links.

The workshop can be built on the left side of town, where most non resource producing facilities are located.

Things can accidentally open if you venture near them and you are hovering on the mouse.

You proably hit a vacant slot , which then tells you what can be built there.

The place where the nodes are, Hellheim, is fairly new,and am not sure how helpful its going to be for you if you spend lots of time in there and havent got enough gold to get the equipment that you will need for the champion to wear.

The bonuses, you get from completeing the floors may or may not be beneficial at your level,dependant on how you are playing the rest of game.

Which Shaman should you use during siege of the SH in CVC  

I think you will find that Raine has been designed for this role,however, depending on how well  developed your shaman are, you might be better off with the shaman that matches your main troop type.
