One of the most important skills a writer can have, IMO, is the ability to handle advice well. But, if you're looking to kill some of the noise, I have two pieces of (hehe) advice for you:
1) If it includes the words always or never, just move on -- and feel free to ignore whatever else that particular advice giver says; and
2) Almost everything people give as writing advice is, first and foremost, editing suggestions. Don't worry about keeping track of it all when you're actually writing.
I have had 3 people read my novel at this point, I find it easy to handle a personal advice I get. I know if I agree, if I disagree or if it's something I need to discuss/mull over for a while.
The problem appears with the editing suggestions exactly.
Some are easy to accept, remember and spot: don't use -lys in dialogues (let the dialogue speak for itself). I have removed all of the stray adverbs, pretty much just left 'quietly' when it was needed. No problem.
Read your stuff aloud - best piece of advice EVER imho.
But then comes stuff pertaining to construction, flow, sentence building, filtering, balancing between pedestrian and purple prose, time to introduce MC, mystery vs. obscurity, limiting PoVs, forcing character 'wants' in the first scene, the proper amount of world building vs. too much, showing vs. telling (while generally a fair rule, I'm still not convinced it always applies) and a whole list of things like that, all of them difficult to judge and decide on.
See? My mind is full of fu--nny advice mess ;P
*Okay, I wrote all that and then noticed that you have a novel completed and are in the process of editing it. This also takes practice and experience. To find out what short-comings the ms might have, you could try using a beta reader. Sometimes betas only know when something doesn't work, not why or how to fix it. That's where the advice might come in handy.
HTH & GL!

Yeah, writing was the easy part for me. I have been writing since I can remember, but I have never attempted to seriously edit my stuff. The problem is I simply don't trust my skills here and I don't exactly trust my judgement. My betas were my friends, but to be perfectly honest? None of them were my target audience to begin with
I got some good advice, but they will have a different view on the book from a genre they don't even really read. Not to mention, writers tend to pay attention to a lot more 'hidden' stuff that can make or break the writing...

I have wrote this novel in ignorance and only with experience I got from my previous writing attemps. Then, when I got to editing, I have found that while a ton of the advices are confusing, some are really simple, spot on, and they talk about the sins I committed a LOT. I fixed those, but it made me wonder - how much else have I sinned?
I can only envy those, who make no mistakes by intuition, but some rules of writing in my native language are also different from English, so I had to consciously find and understand the differences.
Good example, in this case, is using 'said' instead of a plethora other words. Also sentence flow, complexity and some other minor things. Research helped me a lot with this.

I have posted a small part of a scene in the SYW forums, got some very nice advice and applied it in other places. It can be invaluable, I absolutely agree

And thanks for the props, it's been a long trip and I'm afraid I'm at like 3rd "draft". I prefer to call it a beta 2.0, makes me feel like I'm actually on the finish line not in the middle of the way ;D
