Tips for redying faded red hair?

I dyed my hair red. Now I'm wondering if the instructions for redying/touch-ups are really correct, even for dye that has faded very quickly.

I dyed my hair just over a month ago with Schwarzkopf "Red Passion (43)", a permanent dye, and as people have warned me is common with red dye, it's gotten pretty faded already. Some strands are completely blonde again, even. I would like to redye it, but I have a couple of questions:
1. The package seems to think that if I've already got dyed hair, I just need to dye the roots for the full time, and put the dye through the rest for 10 minutes at the end. This seems to assume there is little or no fading, since it's the same instructions for other colours besides red, which don't fade so quickly. Will 10 minutes really be enough to make it all vibrant again?
2. Similarly, there were some patches, especially underneath at the back, and at the ends of the hair, that never were as vibrant when I dyed it the first time. Maybe I missed them when I was distributing the dye. So to get those "caught up", don't I need to leave dye on them for the whole 30 minutes, not just 10?
3. What's the deal with using another shade or a different brand? I have heard horror stories ("Your hair will go green!" or "Your hair will fall out!") or even just that the colour will look muddy. I am happy to stick with this brand and colour if possible, but my local shops are flaky. It is not unlikely that they will suddenly be all out of stock of this brand or colour for months on end at some point. Could I just use a similar red (e.g. Schwarzkopf 37?) if that happened or even a different brand? Alternatively, if I stock up on this colour/brand now, will it go off? Does hair dye have an expiration date? How long can I keep unopened dye in the cupboard?
