fly fishing gear for my father

my estranged father has recently made a reappearance in my life. he seems
tickled to death that i fish, as he spins. while talking on the phone the
other night, he said that if we are going to be doing any fishing together
he might as well get some fly fishing gear. he likes to fish for trout, but
greatly enjoys fishing for walleye, pike and the like. he is coming for a
visit over christmas and wants to pick up some stuff while he's here. what
do ya'll suggest? any help will be appreciated-
