Law is a very "hardcore" subject and as JB says, unless you want to do Law further on down your career then I would think seriously about it.
I would suggest you think long and hard about what you ultimately want to end up doing, whether that is something law based or otherwise.
Don't worry if you don't know what sort of career you want yet as not many do, but do make sure you pick the right subjects that give you the better chance of you finding the career you like. So the obvious question is...do you like law related matter and could you spend weeks (nay, months!) reading the same material to build up a case?
My experience suggests that (not that I have a lot of experience in this ) Law would give you a good rounded subject if you, in a few years decided on something different then you have everything there required by a good degree, i.e analytical skills.
English Language is a good subject to take but, again, you've got to think long and hard as to what degree you want to apply it in. Irony is, an English Language would do well on getting you onto a Law degree
(I'm happy to be proved wrong )
Good luck, I'm sure whatever you decide will be right decision.
