I have'nt touched the brakes since buying the bike apart from having new expensive BB7 spefic brake pads put in to try and stop squeeking. The one's that came with bike need replacing as soon as possible apparantely because there very cheap and are put on just to get the bike cost down to within the bike to work scheme according to salesman. I did'nt buy it on bike to work scheme but now wish I had bought a bike a little more expensive so that no shortcuts were used in the building of the bike. (Is the btws a good thing because of this downgrading trick that all manufacturers are adhering to to reach the magical btws figure).Yes I can reduce the squeel slightly if I back the brakes of to almost not working but does'nt that defeat the object of having disc brakes in the first instance. The shop assure me that it will all go away when the warmer dryer weather arrives. So roll on Summer. Unless I finally out the bike before then and buy my second bike as a much wiser man.
TBH I think the salesman is mistaken at best and a liar at worst,and IMO the shop is just squeezing you for money,if you are not prepared for a little self adjustment and maintenance you're at the mercy of others' if those others are unscrupulous you can be in the do,do and poorer in the bargain .
Brakes,all brakes,come with pads fitted at the factory,Avid make pads and brakes so fit the same pads to the calipers at the factory,unless those are swapped at some time at the bike building factory,which would be highly unlikely,you would have Avid Sintered pads fitted,it's their standard production pad.
There are two types of disc pads that I've used Organic(Soft),Sintered(hard).The O's tend to wear a bit quicker and bed in quicker.
S's take a little longer to bed in and tend to squeal more though not appreciably but last longer.
Both types last a very long time on road/mild off road bikes.
Both types are fit for purpose.
I can only recommend that you set up the brakes as per video linked to,it's a simple procedure that anyone can do,in fact IMO,it's something everyone should know how to do for optimum brake operation.
You mentioned "cheap discs" it appears going off the photos of your bike that it's fitted with Avid G2 CS rotors(I have the same fitted to all three of my disc equiped bikes) these aren't cheap tat they're good kit.
Providing they aren't bent/warped/buckled there's not reason to believe they're the cause of brake squeal.
BTW If you lived close to me I'd offer some practical help.
