Prior to every print, my printer does what I can only describe as a booger prime. It heads to the lower right corner, squirts a blob of plastic then heads off on it's merry way.

This is all well and good, but I have a glass plate that I want to mount and it will knock right into the retainer if the booger has to be placed right there. I guess first, is there a proper name for said booger, and 2. Is this placed by Simplify3D, or firmware, and lastly where do I go to change the location of the blob?

Edit Profile Settings-->Scripts tab-->Starting Script. Look for a command that starts with G1 and has E values in it. G1 means move, and E stands for extruder.

For Instance,

G1 E25 F225 ;

stands for extrude 25 mm of filament at 225 mm/minute. I'd recommend backing up your profile as is, (File-->Export FFF Profile) then make changes and run tests.

Sounds like you have a problem with the glass plate making the bed to thick to me .... Atleast I experienced similar problems with the Wanhao 4S. In general when printing with the glass plate the extruder came to close since the machine did not take the glass plate into account. I found some models to circumvent that like : http://www.thingiverse.com/thing:567385 Which is supposed to get the 3D printer to think it's on the top before it actually is, depending on the thickness of the glass. ( making the sensor touchdown earlier ) This will ofc make the extruder stay ontop of the glass plate at all times. I had to file the circle of that one to make it fit, and I have yet to try it, but the Build Plate leveling now looks promissing.
