OP
Yep - they got it: it's the top link support bracket; better to leave that one on. Once you get more comfortable, you may consider removing the PTO guard - that thing is a total PITA because it has to be screwed/unscrewed in order to move it between the raised and lowered positions. Definitely your call, but give it time.
Ditto on removing that rear PTO cover... a real PITA. Believe it only lasted a year on mine before I removed it. (I know right where it is, still shiny-new....)
