The silver would be where my money would go, the black is a pro bit of kit, unless your planning on buying TB’s of storage and projecting to IMAX then the silver does everything (unless 1080 isn’t good enough for you) In terms of uploading to the web you want to be keeping the settings right for quality vs size especially if your connection isn’t blindingly fast. Vimeo will stop you at 1080 which is sensible as other people don’t want to wait 3hrs for your 5min masterpiece to buffer.
Fast SD is good, I just picked up a class 10 16gb for peanuts – find the sweet spot and get a few. It reads to the PC much faster.
I found I use the Go Pro more than I used to use the camera so I get to capture more of whats going on without worrying about weather etc.
I use Adobe Premiere Pro CS6 for editing and there is a month free trial with the create cloud suite so when your ready give it a go. If you want to keep your raw footage then some external storage would be sensible. I have about 800GB from 2 1/2 years on a HD version.
