Try "Remember The Milk" and Google Apps
I am a fan of Remember The Milk (rememberthemilk.com) for list/task management, Google Calendar for Cal functions, Google Docs for storage/reference and a legal pad for capture.
The RTM "Pro" version (which allows syncing to your iOS devices) costs $25 a year, but I have found it to be well worth the investment. Google has their "Tasks" feature, but I find them very limited.
