early planning stages

netter and i have chosen to visit the british isles for our annual european vacation.  the british isles are comprised of ireland, scotland, wales and great britain.  we are planning on spending about a week listening to everyone speak with an accent, eat pub food and constantly brush aside the incredulous stares when we say we won't be having any alcohol with our meals. 

the main purpose of this post is to solicite advice from any and all about where to go, stay, see, eat, avoid and shop whilst we are in the isles.  we've both been to london and can safely navigate our activites there and in bath, but i haven't got a clue how to prioritize all the beauty and majesty that we have placed on our "go and see" list.  any help to whittle down our options would be most appreciated.

here's a photo from our November 2008 trip in the united kingdom.  really hoping that it won't be nearly so cold, windy and wet while we're there in late april.  a girl can dream...
