Instead of making a decision about Catholicism based on a thread on FR why don't you actually read the Cathechism? Get your answers straight from the source you wish to learn about. The Cathechism gives incredible amounts of detail for the things we believe.
C'mon, it's so much easier to learn about the Catholic faith from someone you know who is a C&E Catholic or from your mother's friend's half-sister who told you what Catholics believe (even though she's never set foot in a Catholic church) than to actually study it for yourself.
