Imo, you should only do Language and Literature if language is a fourth A level. My boyfriend did what you did, only also with French.
History
English Lit
French
English Lang
Just made him a bit more rounded, and has given him more choice of modules during his English degree. This year he's planning on learning Old Norse.
I did both too, as separate A Levels. Big mistake as I didn't go into an English degree.
I did Politics, English Lit, Geography and English Language. Wish I'd replaced Language with Econ tbh.
