.htaccess is confusing – redirect issues

I’ve been having some strange intermittent redirect issues and timeouts causing problems on my WP dashboard and causing slow loading times. My host (Wiredtree) narrowed it down to htaccess rules (seeing redirect timeouts in the logs.) I looked into my htaccess, which I only modified myself to include some 301s and found quite a bit more that I can’t decipher. I’ll paste the htaccess below (minus my 301s) – is there anything in here that could cause issues? I have no clue what any of this means or what plugins may have added it. I had W3TC but have since deactivated it:

# END HGDENY
