We do have a lot of LED switching already though, check out PostServer & AdvancedWebServer

Also... instead of String, please use PROGMEM'ed strings (static const char x[] PROGMEM = "...";) by using ..._P() methods! Current behaviour with string literals is that they are placed into RAM, and every contents will also be duplicated into String buffer. That would be the only improvement I could think of :)

Why changing led pin state in main loop function? You end up with unnecessary digitalWrite call on each loop ;)

Anyway, you should consider adding delay(1) or yield in your loop function. Not sure, maybe http server does that already. This will prevent watchdog related issues.
