It is possible to reach an unlimited value of points and still remain in bronze league. Blizzard's ranking system will randomly 'test' you when it feels you might be ready to move up to a different league. It will put you against a player from the next league and check to see if your 'ready' to move up. To answer your existing question, these players are winning against players they are expected to win against, but losing against players in the next league.
Blizzard views this as a perfect balance. As long as they continue to win, they will continue to gain more points. But as long as the continue to lose their 'test' matches they will remain in that league. Keep in mind that being 1st in a division doesn't mean you need to be in a different league, someone has to be in first.
Both of these team liquid threads give some great information about SC2 ladder and how to move between leagues

Well, like most computer hardware questions - it depends.
What resolution will you be running it at (if you are using an LCD, probably its native resolution). What settings do you want to be able to run it at? (i.e. do you care if you have to turn it down to low settings, or do you want it to look great).
I found some graphs of frames per second on various different graphics cards, and it doesn't seem to require much (which is what I expected) - every card they tested gave good results!
TechSpot did an even more comprehensive review of hardware for SCII. Gamespot summarised the article thus:
The good news is that basically any modern graphics card will be able to run the game very smoothly on Medium settings, so even if you're not someone with a water-cooled monster gaming rig, you'll be fine. This isn't the most graphically-intensive game in the world.
But if you're in the market for a new card, want top-notch performance in the game without spending a boatload of cash, it looks like the GeForce GTX 460 is the card for you. It was recently released and can be found for about $200.
I don't know much about the current generation of graphics cards, but the GTX 460 [is available on Scan] starting from £120, which is within your budget. If you want an expert opinion on current hardware I recommend picking up a copy of CustomPC (my sub failed to update when I moved house, otherwise I would check it for you - WH Smiths usually have it). I think AMD are currently favoured over NVidia, but it's probably pretty close as usual.
Lastly - SCII is more intensive on the CPU than GPU, so double check that your CPU is fast enough too.

Knockout tournaments of any type traditionally use a seeding system. This is to prevent the 1st and 2nd ranked players from fighting until the final, the 1st,2nd,3rd and 4th from meeting until the sem-final etc.
Depending on the tournament structure the number of seeds will vary. The top 16 players or so are ranked as "seeds" and the tournament is drawn up by seeding the programme with these seeds before adding in all non-seeds in a random order. In Tournaments with a number of participants which isn't a power of 2, some number of players starting with the top seeds will be given a "bye" and avoid playing in the first round. This gives a power of 2 number of players in the 2nd round.
