There are a total of 157 main-storyline quests in Avalon. You will leave 'The Wild' location at quest #76 - Speed Of Darkness where you will progress through 'The Wyrd' location. The experience earned will waver from 4,000xp to 35,000xp per quest aside from the final quest #157 - A Great Storm Coming where you will earn 125,215xp for completing. You may get even more xp by doing side quests if you are into that in which case you can find yourself in the mid 80's upon completion of Avalon.
There are lots of factors that play into this. A general rule is that every world is about 10 levels of experience so that would put you at upper 70s to 80? It depends on if you do a lot of side quests etc.
I'm sorry, but I'm not at all familiar with Storm Gear.
It doesn't matter. At this point, only you know what level you will be at the end of Avalon. No one knows what quests you will be doing or not doing, so no one else can tell you.
Wintertusk gear is good, but you might want to look at a couple of pieces of L60 Waterworks gear. There is also crafting in Avalon, so you might want to check out the robe (in Dun Dara), and the boots (The Wild). Don't forget to look at crafting athames.
