Toe-side is always less comfortable; you just gotta kick that back foot to initiate your turning. Imagine a bull kicking its hind legs and kicking up dirt before he attacks. After you get used to it it'll just happen naturally.
NO. Sorry but that is terrible advice. Kicking your back foot to initiate a turn (ruddering) is bad technique and should only be used when absolutely needed. Skidded turns are initiated with the front foot and the rear than follows in a slightly different path, creating a skid.
This thread has some good info on skidded turns and carving as well.
