That is an impressive school violet ! From their website it looks like this organization offers an actual B.S. in Healing, which is quite remarkable. It comes across like quite a bit of commitment is required to undertake something like this, it does seem like it would be worth it though.
I've heard from a few friends in CA that uni is affordable for most there, but comparative to the US and AU universities a 4-year program (the courses offered at the mentioned sch) rank about the same in terms of fees.

Re Healing
The most helpful book on healing for me so far has been Quantum Touch (Richard Gordon) but I haven't read that much on healing in particular. I can state that QT is quite a simple and effective method to learn and practice without too much effort or prior experience though.
