Need a little guidance before entering mid-high range maps

Okay so my PC crashed and died last league and now I have a lvl82 standard league Marauder haha
Anyway Im going to continue playing it to Shaper because I havent gotten this far with any other characters and I want to learn before the next league comes out.

Im running off the build https://www.pathofexile.com/forum/view-thread/1321402

I sort of have a hard time completely understanding the dude who wrote the build, I believe English is not his first langue but the build has helped me get this far so Im very happy..

If anyone could look through my profile (I dont know how to link sorry) And give me a little of an idea on where I am going right and wrong it would be greatly appreciated.

Im currently clearing Tier4-6 maps quite easily just trying to complete the whole map and want to make sure I have the right gear roughly for getting to end game.. I have a few exalt saved for if I need to upgrade so any advice would be greatly appriciated!

Bump.. Is there anything else I need to post or imbed for more help?
