pole barn sub panel

I'm planning a 60 amp sub panel run from the house main panel off a 60 amp double breaker. I'm thinking of three #6 copper conductors (2 hot, 1 nuetral), plus ground wire and running thru 1 1/4" PVC underground, about 80 feet to the sub panel. The sub panel then would be grounded to two rods.

Questions----
#1-What is the minimum size bare copper ground I should run from the house? I'm thinking #8, maybe #10??
#2-What size ground wire should be used for the grounding at the sub panel to the rods?
#3-The #6 copper wires have to have a W in the wire name right (ex. THWN)?
#4-60 amp sub panels that are in stores, seem to be limited to a max. of 4 breakers and don't have a main 60 amp breaker? Are these available or should I just get a 100 amp panel ( is a 100 amp panel ok?) so I can have more spaces?

thank you.

Get the 100, for 6 space main lug panels they are cheap and if you have only 6 spaces you do not need a main breaker in it. You need a min of number 10 ground wire,,, need the W in the wires and I believe you can go to 8 for grounding electrode wire but most of us always use 6 bare.
