ok first off, stock speakers are fine if you want to use them, can just use fader function to have their gain/volume reduced so they won't be so prominent in your system.
from bluetooth, subjective, since it is via wireless medium. you can however have a PMP (portable music player) that supports FLAC if you insist on FLAC and connect it to the head unit via a good quality aux cable. if you can settle with mp3, using usb would be best

actually even active or passive would require an amplifier. considering you're starting out/new, with a very restricted budget, passive setup would be recommended. (typically cheaper since you don't strictly need an active xover/processor)
with rm1k, it is do-able, however you'll have to do it step by step.
suggesting getting a HU + reputable brand component set, may require 2nd hand items if your 1k budget is strict, else maybe stretch it a bit to 1.1-1.3k depending on what HU/comp set speakers you're getting.
power isn't an issue if you're not moving up to amp/subwoofer yet. so for not not something to worry about.
in fact, even if you're on amp/sub, entry level items wouldn't be draining much power anyways unless you're going SPL and/or you just simply blast your audio at ear deafening levels then perhaps it'll be a problem.
actually, sound proofing isn't so much about preventing music going out (although this will be a side effect of it), it is more towards preventing noise from polluting your audio experience, and that is achieved by preventing external noise from entering in as well as internal noise such as your car engine, speakers rattling the door panels and so on.
personally, AT LEAST door panel sound proofing is required, however with your budget, it won't be possible and/or it won't be done adequately enough. (if you consider used HU/speakers, that might be very possible though

)
THANK YOU SO MUCH FOR THE DETAILED REPLY! Really appreciated that!
I've just noticed a couple of spelling errors within my original post.. haha. It's kinda embarrassing ><"!
Okay got it! So I could just use the faders in my head-unit to bring down the output in my stock speakers.
This lead me to think : If I were to retain my stock speakers, would I need to cut out new ports for the new component speakers and their tweeters?
Because right now, my car has only ports at the sides of my doors (All four sides) but they lack a tweeter port.
Is it better for me in this case to install a coaxial setup in my car? Or should I just strip out the stock speakers straight up as they are pretty bland sounding and don't have much dynamic range and a pretty narrow frequency response. Pretty much sounding like crap.
As I understand that most component speaker setups require a separate crossover while I have seen a coaxial with a build in crossover. Am I right on this?

Do you have any suggestions or recommendations for a brand for my component/coaxial set? Is pioneer a reputable brand in the ICE community?
Also, do you have any recommendations for entry woofers? Preferably a smaller one because I don't have much trunk space to spare. Or do you think it's unnecessary given that I'm going for a SQL setup. How much am I looking at after adding a woofer?
Alright! I totally understood your soundproofing part. This might need more saving up for the foam pads. Maybe I'll find some decent deals around here in the forums! Will keep a lookout for that!
Again! Thanks for your awesome assistance. Really love music and it's one of my life's little pleasure when driving.
Edit : SICK GAMING SETUP YOU'VE GOT THERE MAN! Whoa!
