Beginner would love some advice -- Grayling & Trout

Oh boy where do I start? I'm a 20 year old woman living just a stone's
throw from the Tay and am itching to get fishing. Problem is I've
missed the trout season but Grayling seems to be in. I have no
experience with fishing and have no idea where to start. Are there
gillies who teach grayling fishing? Should I just buy the gear and go
for it? And if so what do I need. Oh dear, any help that any of you
guys can give me would be greatly appreciated. And if someone actually
lives near the Tay who wouldn't mind helping out a total newbie in
person I would be willing to pay. Thanks in advance.
