How to run Bitcoin Core both main and testnet on the same machine? I want to be able to communicate with both block-chains via RPC.
Do I need to run 2 instances on bitcoind / bitcoin-qt.exe for that?

Yes. If bitcoin-qt is already running and on mainnet then open up a command shell and type:
>bitcoin-qt -testnet
This will launch a second bitcoin-qt on testnet using the default -datadir= and -conf= options.
The -testnet option uses the folder {default bitcoin datadir path}/testnet3/ and the default bitcoin.conf file by default. If you wish for your testnet instance to have different options to your mainnet instance then add the -conf={file} option after -testnet on the command line.
This works much the same for bitcoind.
