What is your current CYS price on the Best of 2012 compilation? At the very least, you could get the compilation free by buying the greenhouse, but there may be a slightly cheaper way. For example, the Japanese dining set is included, and you already know how to get it for 150 points. But that's not enough to complete Best of 2012, and if it turns out the cheapest path to getting the compilation is simply buying the greenhouse, then you'd end up getting the dining set for free.
Please let me know your CYS on this set too:

Completing Best of 2012 means you could complete April 2012 for less than 70 points. That would give you the deep fryer and the ice cream maker.
January 2012 is counted in a strange way: once I owned More Magic, my CYS on the compilation was 180 points. With some individual items on sale, the cost to CYS might be 63 or 68 points (depending on rounding), which is cheaper than buying the cowplant, also a part of January 2012.
The Gothique Library is not eligible for CYS—I own the spellbook too and just checked.
For the Hogan's set, I believe this is the cheapest approach, for 71 points total:
- DD 151: 20 points (75p value)
- DD 441: 29 points (75p value)
- DD 583: 7 points (25p value)
- DD 521: Hogan's set should be 15 points
- DD 361: I Heart the 50s will be free
I don't know whether the Bohemian Garden set is eligible for CYS or not. If it is, the cheapest approach would be to buy the cheapest item in the set and then get the whole set on the Daily Deal so you get the CYS discount.
For everything else, I think you either have the right plan already or just need to buy the items outright.
