The first question indicates you have a menu but no dropdowns so you get the bar, when you fix the second part the first will go away.
For the 2nd, create a number of pages which you want to work with called A B C D E F G.
From the Dashboard go to Appearance - Menus you will come up with a screen with your pages in a box on the left (titles only) and an empty screen on your right. Actually looks like you have got that far.
On the left box, tick all the titles then "Add to Menu". The will all appear n the right column.
Then drag pages up and down or indenting on he right column, indented pages will be drop downs to the higher level, then save and should be good.
Actually that will be good for hiker therapy on the menu, not sure about the widget col.
