I have to agree with markc, get Combat Companion even if you don't use the new Armor by the Piece/Condensed Combat or Combat Styles it still got other stuff you want like some new cool professions and other stuff.
I myself play with RMFRP and still use some stuff from Combat Companion mostly the new Condensed Combat-system with the Armor by the Piece rules. Our current campaign is a D&D3,5 Adventure Path from Pazio and there is a lot of combat there so I decided to use the new combat system to speed up combat.
Despite the players wanting to. I don't use Combat Styles, it's a good system but think it requires an eye from a GM at all times to prevent abuse so I decided not to go with it. But we have tried it out and it's really good.
Ohh and about the Bardiche depends on how much detail you want, I would probably just go with the regular Polearm table for most types of polearms, since when it comes down to it most polearms can do all three types of crits and work in similar ways and if you feel like the Bardiche won't do Piercing crits just change those to Slashing and then you got more of a cutting Polearm. All this is ofcourse unnecessary if using the Condensed Combat-system where all different weapontypes have it's own crits.
