Here's my setup: Emacs, DDMS + JSwat, and ant to build.
I have emacs and a terminal open at all times. To build I switch over to the terminal and use ant. Sometimes I'll write a shell script to build+install+run on a phone.
My setup is essentially Emacs, DDMS and cscope/find/grep/etc.
I always find Eclipse to be too heavy. I don't do much actual UI coding though (I'm a platform guy), or I might consider it. The ADT UI tools seem to be very powerful and convenient.

Building on the command line is simple. Type ant release or ant debug. Or ant install to build + install on phone.
