Re: Which Stock and Buffer?

Don't underestimate the .223/5.56 round as being too "small." I've taken the .223 out to 1k and while it is far from ideal for extended ranges, it CAN be done with the proper barrel, bullet, etc. (and a decent idgit squeezing the trigger never hurt matters either).
If more of a precision build for longer ranges is what you want, I'd stick with a fixed stock, whether a basic A2, Magpul MOE Fixed stock, or a PRS with some adjustments for LOP, and the adjustable comb depending on how you plan to scope the rifle. If, because of how high you need to mount your optics or your body habitus, you need more comb height, the PRS is the cat's meow. If you don't think you'll need/want the extra comb height from the PRS, you can run a standard stock or run the PRS with the cheek riser lowered all the way.
As for heavier than standard buffers, again it comes down to you and how you want to run the rifle. If you are going to run heavy reloads or you plan on running the rifle suppressed, then I highly recommend going to a heavy buffer like those available from Clint Butler (aka - "Slash") as seen here:
http://www.heavybuffers.com/products.html . Slash's AR-15 XH rifle buffer is just over twice the weight of a standard AR-15 rifle buffer (11oz vs. around 5-5.4oz), but if you are using light loads, lighter bullets, or if your rifle is undergassed in any way, then the XH buffer may cause you function issues.
