Well, you + jan + edwin + aerie would be pretty redundant. You should have an evened out party with 3 fighters and 3 mages. I see u like anomen because he is a F/C. Anomen is a fairly good cleric, but another cleric might be useful, might I also suggest Jaheira. She can take a pounding and heal so that makes her good also(insect plague rocks!)then you will want a tough tank. There are 4 options in my opinion. Keldorn, Minsc, Mazzy, or Korgan.
Korgan definatley does the best damage and hits a lot, but he has a lot of missions when you first get him. also you have to keep you reputation average or he will get angry
(note:
dont put korgan and aerie in a party, they have katfights 
)
Mazzy is a tough little halfling with potential, but is an expert as an archer. she is either a grand master or high master of the short bow, so you can count on some major long-distance damage. but she can also be really good as she is specialized in short sword, which makes her a good warrior too, but in my opinion, there arent that many good short swords in the game.
Keldorn is an damn good paladin that can deal out MAJOR damage. he is also renowned for his auto dispel magic, which can be helpful when party members are scared of dragons etc. he is especially good when you beat firkraag and get the
carsomyr + 5, and even better when you
upgrade it in Throne of Bhall
Minsc is an amazing ranger. how could ya not love him and his hamster boo? they plant their bootprints in the buttocks of evil over and over again. there are many good 2 handed swords he can use so you can expect him to do amazing damage. the only problem is that boo leaves penut shells in my backpack
