level 47 so far, right?
First, your gear is... BAD. So bad I have never seen anyone with such a bad gear.
It's strange that you say your server's MB has huge prices. I heard Excalibur is fairly crowded server, so there should be lots of crafters. No matter what, you should outfit yourself. At lvl 45 you get quest to get some ilvl 50 pieces. About "right side", just buy them from MB. HQ ilvl 70 should be more or less cheap.
Ninjas... are overgeared. Everyone is overgeared, compared to what I see.
Videos... are not needed. In most dungeons all you need is just hold agro and evade AOEs. Quarn's oneshot is exception. Best way - ask before the boss what to do.
