Wifi is certainly preferable to have on when you need it, but I haven't noticed too much drain/issue when no network is available.
Turning brightness down does seem to help a lot (I'm usually manually set to 35-40% which is plenty readable).
Haven't used or needed a task manager since before Android 2.1 came out (mid 2010). Android itself does a great job of memory management, so task managers are largely unnecessary nowadays (most apps will / should sit quietly in the background and will get auto swapped-out by the OS when memory is needed).
