Being is that this is your rookie season. Go polyester resin.
You will likely need more than a gallon, but buy one for now. (you can always buy more resin).
I buy mine from TAP Plastics, but there are many supply houses that have it in stock. Maybe an auto body supply house?
There are two trains of thought. I buy laminating resin and surface cure agent when doing Poly... You build everything up with not surface curing resin and then the last coat you do with resin, add the appropriate amount of SCA.
You will not have a lot of time with the poly to work with it, so small batches reduces waste.
You should be able to find clear KD Douglas Fur in your local lumber yard. You probably have 2X6 stringers.
You will need a gallon of acetone (cheap) and a whole bunch of disposable cheap wood handled paint brushes. Don't forget the wood stir sticks.
Pick up mixing buckets (I use the one quart size).
Grab a couple cheap drop cloths (the white canvas ones) and a couple rolls of Scotch Blue 2" tape. Tape off everything you don't want covered in resin.
I highly recommend picking up a couple or resin rollers designed for fiberglass cloth. Not a fiber roller, but a grooved aluminum roller for squeegeeing the cloth of air bubbles.
You will need virtually three times the surface area you are going to repair in roving and since we are talking Poly, some mat.
Grab a jar of Cab-O-Sil to make a gel like putty to bed the stringers into. Bondo can work, but not nearly as strong.
You are going to use up probably 15 or twenty grinding discs for a 4-1/4" grinder, also cant hurt to have a big 'ol box of rags...
Lastly, get a good quality respirator and if you can swing it, some Tyvek disposable suits. (Grainger) The itch, if your not used to it can drive you insane.
Also pick up some Gold Bond medicated powder and cover yourself in it, it will fill the pores in your skin and prevent the itchies from getting too bad.
Before you rip it apart, measure everything and take a bolt inventory and replace them all, grab a tube of 3M 5200 sealant too... Great chit. (watch out for the sticker shock, but buy it anyway...).
I am certain I forgot some stuff, but this will get you started.
You should plan on having to spend about $400 by the time the smoke clears.
You may want to also pick up some resin pigment to tint the last coat of resin to make it purdy. This is by far the least expensive way to go.
Whew...
