I've browsed several closely related questions already, but haven't found one quite like my issue yet.
I have the following rack, a Topeak Tourist for Disc Brake bikes (with a matching Topeak trunk bag with panniers)
And I have a 2014 Diamondback Century Sport Disc. It has 700c tires, which the reviews for the above rack suggested would be fine. Anyway, clearance isn't the issue at hand. Here's some pictures of the bike - hopefully they're helpful.

Up until now I've been using a hybrid bike with no panniers... so I have next to no familiarity with racks. I've looked into the issue, but feel increasingly suspicious about whether there's any way to mount these. If I can I'd be most pleased, although I'd need the method pointed out (and I've experimented; for example, you notice the two bolts above the quick-release lever in the last picture? those are too large to work double duty for the rack; they don't fit the thing) - but if not:
- I've heard stuff about p-clips (like Halfords 19mm Luggage P Clips - again, no link). I'm not sure what problem they exist to resolve; it looks like it's mine, but - there's always two different places to attach a rack (triangles and all that), plus more than that in different styles of rack (some attach to a seat post, apparently) and I'm not entirely sure if these would help my issue or the one I'm not having.
- I heard a recommendation for the "Tubus Adapter Set for Quick Release Axle Mounting." Ignoring quality concerns (I can make a judgement call), would that be a good purchase for me in that it might resolve my problem?
- Same for the "Tubus Clamp Set - Rack Eyes for Seat Stay Mounting," which is apparently related to p-clips.
