[CQ-Contest] SO2R Questions

I'm in the process of converting my station to SO2R and need some help...

I have 2 MP's, one amp (for now), and one set of antennas (for now) 
consisting of a tri-bander and several dipoles, all fed through one coax 
switch in the shack...

My biggest concern for the moment is antenna selection/switching and 
filtering, so as not to blow up one of the MP's front-ends...Been 
reading everything I can find on this, but unfortunately, I'm don't know 
enough about it to fully understand everything...

I have two main questions:

1) What are all you SO2R guys doing for antenna switching?

My idea for each radio chain is to have the MP, each followed by a band 
decoder, each followed by a bandpass filter (Dunestar 600?), each 
followed by an amplifier and then the antenna system...What do I use 
between the amplifiers and the antennas to have the correct antenna 
switching performed for each radio? I'm assuming it can be setup to be 
done automatically? If so, how ? The other alternative is to have one or 
two antennas assigned permanently to each of the radios and manually 
switch them with two normal coax switches (one for each radio)?

Second question...

Any advice on which of the SO2R Controllers would be best for me ?

I plan on having a seperate computer for each radio and each 
radio/computer will be setup for RTTY, CW and SSB contesting...

Sorry for the (probable) simplistic sounding questions, but I'm new to 
SO2R and want to set it up right...I'm sure there are a thousand ways of 
doing it, I'd be interested in any ideas...

Thanks and 73,
