Yes, you'll need two distinct key pairs for this. Different user IDs on a key pair are more or less simply aliases. If you export your public key to send it to someone all user IDs are included. Unfortunately KMail currently only supports one (global) PGP user ID. Therefore you'll have to change the (global) PGP user ID everytime according to the key pair you want to use. Different PGP user IDs for different KMail identities will (very likely) be supported in an upcoming version of KMail.
