Is there any documentation that matches colored wires (db9 side) to enumerated 'gold fingers' (rj11 side)?

It depends on your use. Google the various pin outs for rj11 and connect them accordingly.

First of all sorry for my English. I don't figure out, how to make a bridge between 4 - 6 & 7 - 8 with this adapter on each one

The pins can be inserted in any configuration you want . Also you can short wires if need to .
