Another problem could be avoiding spamming the view list.
I'm not clear what you mean by this.

We talked about it on the irc. Leon (user) put the second on the top100 the Leon (article) with a tiny script in minutes. So it's not very reliable.
Keeping the information on the WM servers should be done very carefully. The page counting could also affect the wikis flow (did you realize images are kept on other server so if it's overloaded, you can still read the articles?). The automatic page counting is disabled on wikipedia for the load it would give. Archiving on the db should be discarded i think, at least on the *same* db. There's also little need for the full replication of statistic data.
What would be neat would be having the tools recognizing the users. Configuring tools. the deletions browser available for those with deletedhistory, configuring with monobooks.js... Hopefully, the single login should give some external auth system.
