For the first one, you can actually edit the text speed on the File Select screen.
For the second one, you can backwalk everywhere or sidehop -- the first is accomplished by looking in the OPPOSITE direction you want to go in, Z-Target, then start walking backwards. It's the fastest method of travel by foot. The second is accomplished by looking to the side of the direction you want to go, Z-targeting then jumping to the side, it's the second fastest method of travel by foot.
I feel having to manually edit the options is a bit tedious, but hey, what can you do?
