If the LHS is a store with lots of selection, I would make the 2hr drive, as I drive 1.5hrs to my LHS it is worth it in the long run.
My #1 reason I suggest this is because pads dont always fit the way the sizing charts suggest.
It's a pain in the you know what, trying to deal with returning pads, only to try others, and return them too. (My friend did this instead of going with me)
When you are getting your initial set up, you can try on all the sizes and models of pads and helmets and find what fits you best, and after that you can place orders online since you know your size/model.
Everyone is built differently, and what fits one guy, might not fit you.
Even the shape of your head will dictate what model of helmet you should get, and the wrong model of helmet can give you headaches.
I went to my LHS when I was starting to play again after a 10 year absence, and I have a mixture of brand/model pads, but they all fit me and I'm very comfortable when playing.
