I’m having a problem where my extruder gets filament goop on it then drops down onto the print ruining it. Is there something simple I’m missing, because I can’t seem to find out how in the world the filament is getting up there.

How long have you been using this particular printer? In certain circumstances, if you've run some more abrasive filament through the system and you're using a brass nozzle, you can get extrusion which occasionally gets caught on a worn edge of the nozzle itself and curls back, beginning to make a glob depending on which direction the head was moving at the time. That can mean that you just need to replace your nozzle, which is a little bit of a pain but definitely within the realm of possibility.
The problem could be completely different, depending on how that group is forming and where, exactly, it's forming from. We might need pictures.
Thank you for jumping in to answer that. :-) I'm sure I will experience all these issues along the way myself as i get started.
My pleasure. 3D printing is still very much a tinkerer's art as much as it has any science, and you have to be willing to get out in front of it and understand that problems can have many sources.
So far I've been extremely lucky with the low cost printer that I chose to be my primary, but I am trying to stay aware of all of the problems that can come up in the course of operations. That is a lot of continuous research and staying on top of things.
I am looking forward to this new adventure ;-) Thankfully @themarkymark has given me some guidance on what to expect so I don't drive myself nuts with the little problems that pop up along the way.
I will definitely share my experience doing this to help others as well.
