You can disband the HRE, but you need to occupy the capital of of the HRE emperor and all of the electors (or have electors as vassals).
I think if you form the Netherlands you actually join the HRE properly, which means you can fight better within the HRE itself without calling in the emperor each time.
If you join the league wars on the protestant side, you can make protestant the dominant faith, this normally screws up Austria quite a bit who typically stay catholic. You can even flip to protestant yourself which has some good bonuses too compared with the papacy.
England kind of suck as an ally actually, they rarely bring troops to the mainland, tbh they are probably a good expansion route for you in terms of taking land outside of France/HRE. London in particular is a centre of trade in the English Channel and will give you a nice trading boost.
