This is how my druid is spec'ed, I actually have 2 healing specs, one for 10 man raids and one for 25 man raids, this picture shows my 10 man raid healing spec. There are not too many differences between my 10 man and 25 man specs however there were a few things I found to be more beneficial when healing 25 mans. You can of course just copy what I've done for your druid but I would suggest instead that you look into the skills yourself and spec towards your style of healing, because quite possibly you do not heal the same way that I do.
