I found tanglewood much more helpful, personally, than ambleside... though I know lots of people love ambleside more than anything!
Another good site is simplycharlottemason. Very helpful.
I just switched to a Charlotte Mason style a couple months ago. We're not completely, strictly, literature-based, but we've greatly upped that aspect of things and incorporated (or are in the process of incorporating) other CM ideas (in regards to narration, scheduling, planning, nature). DS is almost 11, and is really enjoying it.
