By also not allowing splats in with freedom I stop all the spells from them just coming into my game. Don't forget clerics and druids know all their spells and there are some pretty powerful spells in the splat books. As well as some feats that I don't necessarily want in my game.
DM control over splats can reign in some degree of powergaming, but not all. The classic CoDzilla argument was that the divine casters have everything they need to be overpowered in core.
10.) Priests, Druids, and lower tier groups that gain 'all' spells on their home list get Prayer books/Training Books/etc that function as spellbooks. I worked on this at my blog before I got injured, and plan to return to the idea with vigor once I can crunch better as this post has taken me almost 45 minutes to generate and I'm worn out.
I've considered the idea of prayer books for clerics before, but I also wouldn't want them to be the cleric spellbook either. And flavor wise, its doesn't really feel right for druids either.
Not sure about this one to be honest. For one, most of the spell components (unless you also want to go through every spell and change those) are hardly rare or difficult to get. Pinch of sand for a sleep spell? Not exactly hard. Some might be a bit tricky, but, for the most part, it's not a huge deal. And the casters are already getting reamed with book keeping. I'd also point out that this only really affects wizards as the cleric and druid are mostly using their focus.
Yeah, it's like I said above, cheap spell component tracking is a lot of bookkeeping for what are trivial resources. It doesn't really solve the power issue.
