Roy on "Want to show Excerpt rather than full posts on home page"

If you have a complex theme and you don't know your way around the files, this could be a bit of a pain. Just go to the plugins repository and find yourself a nice excerpt plugin. They are much more flexible than using the_excerpt anyway. I use Excerpt Editor to show one post in full, the rest in excerpt, it has settings for different archives, the length of the excerpts, etc. and all that from a settings menu in the dashboard.
