Few Minor Issue's

I spoke to the previous owner and he too knew about the rotor but the point of impact was so tiny and had no effect on the rotation of the wheel. Which is true, but i can hear it which will drive me insane i can't just ignore it.

If it's small, just find the part of the disc that's rubbing and push the disc the other direction with your fingers. You're only trying to bend it fractions of a mm. It's not the most accurate method but it works . You can use something like an allen key if you require a little more leverage.

 

Alternatively, find some muddy trails. You won't be able to hear the pad rub over all the grinding.

Pretty easy to straighten a rotor, find the high spot and then lightly tap it with a hammer, spanner head etc, LIGHTLY being the operative word, light tap check the run out, another light tap, check again, repeat till happy . Quite easy to send a rotor into the bin if too eager. DO NOT TRY FOR PERFECTION, just work it till it's acceptable, perfection is only possible for the first few weeks after fitting brand new brakes and rotors and then never again . Also make sure the brake calliper pistons are centered..

 

Make sure you clean the rotor/pads with alcohol or brake disc cleaner after getting your manky fingers and what not all over it, or accept that you may contaminate your pads.

Some chain guides have rollers and some don't. 

 

From the pic, its seems like the clutch on the derailleur is in the off position, maybe that could cause the chain jumping off?

 

Another language to me, but i shall do some research! Thanks!

Please don't hit rotors with anything.

 

Rather bend with careful finger pressure. Be careful as edges are sharp so use a rag or some flexible cardboard for protection if necessary

 

Alternatively there is a Park tool device with a deep slot in it for bending discs.

Or a shifting spanner.

 

If you have a perfectly flat anvil you can peen a rotor straight, but a shifter or rotor truing tool is a far easier way to remove small warps.

For fks, if you are useless at hitting things, yes don't hit your rotors.

 

I use a little copper hammer to true my rotors, I find it more accurate than fingers or a lever/shifter, maybe a copper hammer isn't what most people will use but judicious use of whatever tool you do the job with is what's really needed, its quite easy to make wavy rotors.
