I need to tolerance a dimension in a drawing but the box to change from Nominal to something else is grayed out. How do I do this? Also how do I add center lines, dimension countersink max diameter (need to pick the outer points.

Here is another example of where I need dimensions that I cannot seem to drop in. It does not recognize the endpoints of the keyway slot. On the larger dimension it doesn't know that it should be dimensioning from the bottom of the key to the shaft OD because it splits the shaft OD into to pieces. No dim is dropped. Is this another toggle that needs to be moved to YES?
On the same note, how do I get the section line to show in my main view of where this section B-B is taken from? 
It's all about where you pick and where you place your dimension. First I would suggest to create your model with those dimensions and then just show them in the drawing. I know sometimes this is not possible or not practical or not available for some reason or another.
To create the dimesions in the drawing for the cutout width, pick on the vertices and place where shown, you should get a pop up asking horiz vert or slanted, you'll select vert.
To create the cutout depth, pick the circles as shown and then place as shown, you should get a pop up asking tangent or center, you'll select tangent and also then a pop up for horiz also.
You can also use the intersect between 2 lines (or edge/axis) to get more exact but more picks.
The view arrows are in the view properties, section tab.
We all knew I would have another question: I have my key cut in the shaft model as shown. I then create an assembly to add a plug. The drawing is for the shaft assembly and will not show the keyway angle dimensions. It seems sometimes it does and sometimes it waits until I try a handful of times. What is driving when this shows up? Or how do I create a line that is from the center of the shaft to the midpoint of the key? Any line I draw does not seem to be constrained to the centers.
My last question will be with a BOM table that I brought in. Item 1 is tied to the part name for the description. Is there a way to unlink the part number and and description? On some of our assemblies we call for part number we say see Note 1 and the description will be bar stock. Normally I like the linked, parametric idea.
To show the dimension of a part feature in the drawing of the assembly, you have to select the feature that has the dimension, not the view when in the show annotations . It won't show all the dimensions of all the parts of all the features when you select the view of the assembly. You can imagine a large assembly would show thousands of dimensions, not a very productive pick. In the image below, I picked the seal groove feature of the housing within the piston assembly.
Your BOM table will be handled with repeat region relations. Depending on exactly how it generates the information is usually company specific but is generally mostly generic stuff. Look at this link and see if it applies...SUMMARY: repeat region relations to change a name
If not, you'll need to provide more info on how your bom table is constructed.
