You should absolutely be hitting the water temple at this point in time. It should be a breeze for you if you have darkness. After that, I would suggest getting your ToEF preparations ready. At level 22, you shouldn't have any real problems. An alternative is to build up your climbing and stealth skills, and hit the Rift. This will net you 5 SoCRs plus a huge pile of useful spells.
As for your other concerns...
What alignment are you? If you're neutral (N= works best in my experience), you should check the Dwarven mystic in Dwarftown. If he's feeling generous, he'll leave you with 4 SoCRs. If you have ball spells and at least 32 Willpower, you could try bugville I guess, which gives you 3 SoCR, but it's very dangerous...
Crowning doesn't have an artifact limit. Only pre/postcrown does.
Bless spell can't be used on items, but remove curse can be used to keep corpses from rotting.
Animated forest isn't a problem unless you kill the trees with fire. That will make them all hostile, but killing a few here and there won't. With invis + dual shields, you should be able to get through easily.
The other point is that, honestly, corruption is not a huge deal. Not having any removal is annoying if you get hit with stiff muscles or something, but 80% of the corruptions are fairly harmless, and several are quite beneficial. If you don't waste a lot of time, you can probably get by without needing too much of it.
