Task app that includes hierarchiacal/parent-child function

[tazcubed]

I'm looking for advice in finding an app - in this matter, either a task or project management app that does the following:

1) include hierarchical/parent-child functions
2) can connect to 3rd party email/calendars (I'm using MS Outlook)
3) Includes the ability to divide into projects
4) Can set reminders (both day of, and specific time).

A nice to have:
- gantt style charting

If you can include pros/cons I would appreciate it.

As an aside, is there any way to search for apps based on a combination of name/type and ranking?

Thanks in advance!

Anyone have any recommendations?

"Outliner" - syncs with different desktop programs or through the web service "Fargo". Sorry, I haven't used it enough to give pro's and con's. I got it as a portable "Ecco" program, if you're familiar with that venerable program.
