Not meant to be snarky at all, but have you tried using the forum search function? There is a massive thread regarding Fraser pinks every time the run comes through. Lots and lots of posts full of great info that will cover all the basics.
The 2013 version:
http://www.fishingwithrod.com/yabbse/index.php?topic=33431.0There's 58 pages so that should keep you going for a while
And just googling 'fishing fraser river pink salmon' will give you a lot of great articles and videos too, some from this site.
By all means, ask your questions, and we'll be happy to answer though you can find a lot of the answers yourself with a little searching.
As far as your last question, yes it would historically be considered a little early, though I wouldn't be surprised if some have already started to trickle in. Only one way to find out!
