Live Setup, Live Options

[Sideout31]

Hello everybody. I'm new to this site and to programming in general. I am trying to figure out a live setup and am curious as to what will do the trick. I don't want to just push "play" on protools and let the tracks go. We'll have guitars, Rhodes, kit, but I want to know how best to perform the beats and some ambient sounds I've made live. I know I'll have to trigger them somehow and I'm wondering how to trigger them while our drummer can still play to a click. Do I need to use Ableton? An MPC-2000? A Boss RC-20 to loop Rhodes? ASR-10? I don't have money to just try stuff out and see what works, so I want to make the best effort at researching and getting everyone's input. My style of music is most like Bjork's. I don't know how she does her live setup. Please help me and give me your 2 cents worth. Thanks.
