hmm... i'd rather not play the psychic warrior. i hear that they're fairly broken (though i'm not sure why? the lack of PP seems like it would keep them from being too over the top) and also, they just don't do the same thing for me in terms of flavor, or cool mechanics (i started off with the barb, so i could ease myself into the system, but i'd much rather play something that's more exciting.)
if possible, i'd rather not take the soulbow PrC: firstly, the GM is really story driven, meaning that during the character creation proccess i had to justify why my dwarf was a barbarian, before he'd let me choose that class (i get the desire to tell a story, but... really?) and trying to convince him of allowing that sort of thing is more than i'd want to deal with... secondly, it seems to be completely counter to the idea of a soulknife (a dude who has been making melee weapons this whole time, suddenly has an epiphany and decides to shoot them instead?) and further, standing back gets fairly dull IMO. so i'd like to really focus on that idea of TWF, even if it might be sub-optimal.
I WILL, however, definitely look into multiclassing into ardent. but, wouldn't that make the character fairly MAD (as i understand, the ardent is a CHA based class)?
