with no weaponspecc its still smart to wear a dagger in the offhand, because it hits faster therefore the poisons stack faster. this can add some advances in some cases (not using shiv with crippling poison for example).

on leveling you cant choose weapons for your rogue anyway, you have to pick up what the goods of droprate or questsrewards give them to you usually. as long as you dont do things like sinister strike with daggers, or try to ambush with a sword in the main - everything will work fine if your specc fits with your weapon (meaning weaponspec also, which is often an endgame question only).
