Creature Catalog proposals (and any monster article proposals) should go to Dragon, but if you send it to Dungeon and get a "please send this proposal to the other magazine" reply, don't worry, since all the editors for both magazines are kept in the same room here.
As for updating old monsters... that's a bit of a hazy realm. We can't just reprint a converted stat-block for an updated aurumvorax that appeared on the web, but we can print an updated stat-block for an aurumvorax that was built up all on its own. The resulting monster'll be similar to versions posted online, but it won't be the same. An entirely new monster that goes up on the web can't be submitted to the magazine. If you publish stats for a sharkmouth monkey on the web, we won't publish a sharkmouth monkey in the magazine. That said, parallel development happens all the time in this industry, so it's not uncommon to see variants of sharkmouth monkeys show up in multiple sources (especially if a movie called Sharkmouth Monkey came out recently). In general, it's best to constrain your submission to updated monsters from old editions of D&D or to entirely new monsters.
Mmmmm... aurumvorax animal companion...
