1. mouse to move the screen is how i've been doing it, but i would prefer cursor keys as well or WASD map movement.

2. left click on npcs, then look in the lower left for a button to interact with them. mousing over that button will usually tell you their hire price if they are adjacent to one of your units, or in your territory.

3. click on the city, then look down on the right for the little circle representing your sovereign. left click him, then right click outside the city somewhere.

1) Since supcom I use zoom out-zoom in to move the map. Sometimes I click-drag. No need for cursors I think.

2) Like Wizz2mo said. Even if the icon is a sword, don't be afraid to left click, you'll have the option to hire the npc. The npc needs to be in your territory or next to your sovereign

3) Like Wizz2mo said. If you click on the little shield next to the medallions you'll have a list of all your units in the town. When you have an army, you can also click the little shield to get a list.

Just holding down the left MB and dragging works for me.

I still prefer using the keyboard to move the map.  Control-wise, I guess you could say I play strategy sames the same way I do FPS' on the PC.
