I want to have some new characters in my party but I would like to know how to find Keldorn and Hier'Dalis (or something-the blade guy).

Keldorn can be found in the Temple district sewers once you've accepted the Unseeing eye quest form the priest.

Haer'Dalis can also be found in the temple disrict sewers behind a secret door at the north of the sewers.

If you've already met Keldorn in the sewers and chose not to accept him right away, you can find him at the Paladin Stronghold in the southeastern corner of the Temple District. Haer'Dalis is always in the playhouse.
