1: correct, although I don't know the correct link. Just take the one from the page
2: IIRC make a user.txt and put your username inside; the teamname must be in brackets and has to be added to your username: "the-mk[Free-dc.org]" for example.
3: non required. Just upload work!
4: see 2;
5: see the other current thread
6: depends on the precalculated results you have in results.dat; if you start with a fresh installation (and thus results.dat is empty) new results should pop out after 10 minutes or so. Later it could take hours to finish a workunit. The points you get are calculated based on the quality of the result (the muon-yield), and so if it takes longer to calculate you get more points. Don't worry if it takes ages, you'll get even more points for that!
7: Only Firedeamon (or Firedemon?) AFAIK ....
Be sure not to use the graphical version but the textclient ... you know why (=> speed) .... although the graphical client has very cute graphics ...

PS: all the data refers to older version of the client. Haven't used it for say half a year. Should still be valid though.
