Back to topic..I don't think any of those you've listed will do Al if I'm honest.You really need Allen keys, chainlink removing tool, flat & Pozi double ended driver and a bike spanner - that's it...Oh and a puncture repair kit too.
I have hardly needed to use it to be honest. I haven't been riding this last year but before that I used to ride on a track in a pine forest just over the road and all I have really used it for is adjusting the seat and a mirror. The reason I bought it however is because my chain broke on a trip in the mountains miles from anywhere, which made getting back a bit difficult. My mate who runs a bike shop recommended it saying it has everything you need and nothing you don't (he could have tried to sell me a more expensive one he had). On that note I would add a short length of chain and quick link like in haerathus' picture.It's probably a bit late now but I would make sure any cheap drink bottle is safe and the plastic doesn't break down (BPA free) - I stopped using a couple of my old ones as they make the water taste nasty, god knows what chemicals you are ingesting.
I usually carry a Micra or one of those Lidl bike multitool sets. They are good for the odd minor adjustment (saddle, a loose screw..)I think it will be more likely you will need to repair a puncture, rather than do serious maintenance on the bike.It all depends on how far your are cycling, for how long, the road surface, whether you are alone (if your companion carries tools you will not need to)
If you're looking to learn about fixing the bike yourself, you should take a look at http://www.sheldonbrown.com/ (an eclectic mix of informative and interesting articles about all sorts of bike related topics) and http://www.parktool.com/blog/repair-help (lots of in depth maintenance and repair info).They're not that complicated, but some of the 'features' of bikes can be confusing. Good luck!
