Audacity is the only full-featured free editing program that I'm aware of, unless you can locate a copy of Spark, which is no longer in development and isn't Intel-native. On the lower end of pricing you've got Sound Studio ($79) and Amadeus Pro ($40). Rogue Amoeba's Fission may be worth a look as well ($32). So there's your free editing/tracking.
xACT can do tagging, FLAC/mp3 conversion, cdparanoia (the Mac/*nix equivalent of EAC) and checksums. It'll even output a basic track listing/timing if you feed it files and track names. Absolutely free, though Scott (the developer) actually likes XLD better for ripping.
Torrents, I'm also a Transmission man.
And for burning, I've settled on a program called SimplyBurns because I've ditched my old illegitimate software now that I've upgraded machines and think Toast is a total ripoff at that price.
