phranque - 5:27 am on Jan 8, 2009 (gmt 0) the pages at those urls are already indexed.
you are probably looking at "URLs restricted by robots.txt" in the Web crawl Diagnostics tab.
have you also checked the "Analyze robots.txt" option in the Tools menu?
someone might actually be linking to those urls.
you have to decide what signal you really want to send the bot.
for example, you can tell the bot "go away" (Disallow) or "there's nothing here" (404) or "go somewhere else" (301/302) or "take this" (200).
there are other response options, but Disallow doesn't mean "Forget about it".
