Less English action? Unlikely 
Not sure about beer instead of tea, whatever next! Definitely time to see what happens in Germany.
Well, it helped clear my head, didn't it? Got me through two academic degrees, too. Next would be jenever, that's the Dutch drink Brits could neither spell nor make (turning it into gin, which is only good when mixed with tonic) - sorry, turning into a rant; tea does seem to work fine for you.
I wasn't supposing you'd sit still, just that you'd show us the chaos in some detail. I'm happy to see Germany all diagonal stripes and some of them not even in your colors.
Your goals for the next 100 years look fine to me. Seems to me you can let the Germans take care of themselves for a bit. As long as they don't go Questing, of course. Cutting Burgundy off from the sea is necessary (and legal and right, to quote another upstanding British leader). IMO you'd do well to also cut the Hansa off from the sea, to prevent Burgundy winning another outlet, to prevent another possible colonizer, and to take out a republic.
Sealing the entire European coast doesn't look feasible. You can and should take on Questers with short coastlines, but if Milan takes it, that's no remedy. Your best bet against colonization would be rapid colonization of the American coast, starting with the US/Canada area. Next victim: Shawnee, Creek or Cherokee, whoever owns the US coast. I'm sure you're on it anyway.
I agree with GaiusC that you should bite the bullet on Crete. It doesn't seem likely that others will take over the islands and if they're republican, they need to go before R/RC. If monarchical, it's better to take them with R/RC as they'll be BB-cheaper and warscore doesn't play a role. Same for the non-Europeans, just take your cores and otherwise ignore them, they're no threat, they won't become expensive in terms of warscore, and they're very unlikely to turn republican on you. I think you can wait and see if you get a border dispute on Avignon too, no hurry there at all. Your second goal, while important, is probably least time-sensitive.
I think you have enough time: 100 years at 3 BB burn/year = 300 BB. The pagans require only 32.2 BB (5 Aztec, 3 Congo, 6 Mutapa, 9 Iroquis/Huron, 18 Creek/Shawnee/Cherokee = 41 provinces x 0.8), that leaves 270. Everything outside Europe is a monarchy, so you can take it with R/RC. At 2 BB/province, you can take ca. 130 European provinces before the Revolution CB.
