I would start out with WF5F fly line. That stands for Weight Forward 5 Weight Floating.
Here is a chart fly sizes to Tippet sizes. I think this is mostly for some Orvis leaders, but it's almost standard for anything else I think. Notice.... Like anything else in life this is just a guide.
Fly Size_____________________Test_______________Leader Or Tippet
#4-#6______________________15.5___________________ 0X
#4-#8______________________ 13.5___________________ 1X
#4-#10_____________________ 11.5___________________ 2X
#6-#12_____________________ 8.5____________________ 3X
#6-#14_____________________ 6.0____________________ 4X
#14-#20____________________ 4.75___________________ 5X
#18-#26____________________ 3.5____________________ 6X
#20-#28____________________ 2.5____________________ 7X
#20-#28____________________ 1.75___________________ 8X
I only use 2X, 3X, 4X and 5X tippet.
On my 6 wt I use a 5X leader in a 9' length.

Then you will want a ton of other stuff too. You will want fly boxes and there are sevral makes and models. I have some NIB Okuma fly boxes with ripple foam in the bottom and clips in the lid I am getting rid of. Just not what I want in a fly box for myself. I will be getting Double Nubby Tack, Bug Luggage or Fox Box fly boxes from now on. A good vest, fanny pack or a chest pack is nice to have. Forceps, clippers on zingers, extra leaders, a tippet tote(I have one that is just a piece of bungee cord on a clip... works slick and it's the best one I have tried.), and there are lots more thing you will want.
Lots of options, just pick your stuff and go with it. You will end up buying more.... trust me. I even got into fly tying and now tie for a few shops and friends. It can get adictive fast. :D
