Multi-use Tools:
Utopia Angel
Utopia Angel contains intel formatters and various calculators.
uTools
uTools offers up a more user-friendly display of the game and a vast amount of features.
Utopia Seraphim
Utopia Seraphim is basically Utopia Angel, but compatible with Linux (and Windows).
Ultima
Bijo's Ultima. Similar to everything else. A nice multi-purpose tool.
Intel-Storing Sites:
UtopiaPimp
Pimp is the original (redone) and most popular intel-storing sight. Will store all your in-game intel and track ops/armies.
Utopia Organizer
Another little intel-storage site. A possible alternative if you aren't satisfied with the first two.
UpoOpu
A nice looking intel intel storage site with a unique layout and functionality. Not recommended for tablet or phone users, touch-screen limits a lot of functionality of the sight.
Other Tools:
LucidBot
Java-based IRC bot. Supports over 150 commands and can help with chaining.
Stas' Detailed Menu
This is basically a very simple version of uTools for Chrome. It just enhances the game's menu with more detail.
Seraphiel
Another greasemonkey script to improve user interface in the game.
Utopia Prince
Classic news formatter. A few bugs plaguing it though...
Utopia Seraphim Online All-in-One Formatter
Best News formatter out there afaik.
Utopia-related Sites:
The Dragon Portal
Features a LOT of utopia-related things. From the old guides, history of the game, to up-to-date tools.
Utopia Reading Material:
A lot of this material is out of date, but still may be interesting to read.
Utopia Temple
While Temple does still update Angel, most of the community interaction has died off. However, a lot of the utopia culture is still on display if you'd like to see that culture in it's hay day.
Some highlights for temple:
A basic FAQ about Utopia
ASF is robbed!
Muaddib's Strategy Corner - Learn about (old) mechanics
Hel of Dim Forest
Arguably the coolest prov/story ever in Utopia. Curious? Read for yourself if you don't know the great tale :)
Rosedragon's Virtual Utopia Guide
A cool little guide for Utopia. It guides you through the game and explains things as you go. A bit outdated, but still fairly relevant.
Morbo
Legendary tale of Morbo. Morbo lands in a ghetto. Hilarity ensues.
IRC channels:
Common IRC channels for a new player to visit. Most utopian's use the utonet irc server
Server: irc.utonet.org
#Strategy (for strategy discussion. Lots of player idle here)
#utonews (The forum news team's channel)
#uTimes
#dragonportal
#recruiting
Plus most kds have public channels, so just ask around.
