Well, from what I've seen, from your screenshots, you have an AMAZINGLY strong army, so what I would suggest is that you use said excommunication.
Strike the factions you are at war with, strike hard, and take as many cities as possible.
Once you start running low on troops, give the Pope a huge sum of money and ask for recommunication, or just kill your king (Recommunicates you either way).
After doing that, make peace with a faction or two, getting them off your backs, and continue the war against the others, and STAY OFF THEIR LAND, let them attack you!
If they come into your land, fight them, if they don't, let them stay out!
You will lose reputation and Papal favor if you attack them on their lands - The lands you just conquered while being excommunicated will get you up and running, just hold the fort and start asking for peace, sooner or later, you should be fine.
If you want more help, go to the link provided by Infantry at his earlier post, or go to my guide (Signature link), I have a Venice guide there you might be able to use.
Good luck!
