Any input would be appreciated.

Not sure I can help . I have an EQ-2 which is similar.
That altitude bolt - which is that?
I thought it had a 'bolt' down the centre holding the mount to the tripod [Azimuth lock knob], with a three pointed nut to tighten it up. Normally you line the mount head up with one of the legs then tighten this up properly and forget it.
There is a screw-bolt for setting your latitude [Latitude Adjustment T-bolt]. Again, when you have set your latitude on it you normally tighten the lock bolt [Latitude lock T-bolt] and forget it.
The other controls are the Right Ascension and Declination control clutches [lock knobs], which are loosened for rough pointing, then tightened just enough to keep it in place, after which you use the slow motion controls to point accurately and follow an object in RA.
Orion have some good views and manuals:

Also the manual (Orion's tend to better than the 'skywatcher' equivalent has a diagram naming the parts:
