Here's my army; what heroes or Captains should I get for my Gondorians?

My local GW manager is badass and he's making some calls and getting me a shipment of a bunch of OOP Dol Amroth Men at Arms and Foot Knights because I really am not trying to buy Finecast/overpriced minis. So expect Prince Imrahil foot and mounted, as well as more Foot Knights of Dol Amroth and Men at Arms of Dol Amroth.

Infantry
60 Warriors of Minas Tirith [420 points]
2 Warriors of Minas Tirith Command 1 [100 points]
2 Warriors of Minas Tirith Command 2 [100 points]
4 Gondor Commanders [200 points]
3 Osgiliath Veterans
1 Beregond [25 points]
6 Minas Tirith Citadel Guard [48 points]
3 Minas Tirith Citadel Guard 2 [24 points]
6 Minas Tirith Citadel Guard Archers [48 points]
4 Guards of the Fountain Court [40 points]
3 Gondor Avenger Bolt Thrower [70 points]
6 Foot Knights of Dol Amroth [54 points]
2 Foot Knights of Dol Amroth Command

Cavalry
11 Knights of Minas Tirith [143 points] <----6 of the plastic ones and 5 of the older metal ones
1 Knight of Minas Tirith Standard [13 points]
6 Knights of Dol Amroth [54 points]

EXPECTING TO SOON ACQUIRE:
1 Prince Imrahil of Dol Amroth (Foot and Mounted)
2 Knights of Dol Amroth Mounted (OOP single ones)
3 Foot Knights of Dol Amroth

I wish there was a GW near me I have to drive an hour to get to one. I buy most of my stuff online (eBay is my best friend for GW)
I am working on a Gondor Army as well.

I have 84 Warriors of Minas Tirith and 6 Knights of Minas Tirith.
Working on a Grey Company to ally them with.

I really need to boost my calvary.

Good luck with your army my friend!

Damrod is a cheap captain. Madril has a useful special rule for scenarios with reinforcements. Both are covertable from Gondor Rangers. For Fiefdom, Forlong is more than worth his points---especially if you play a smaller army and can't afford Imrahil.
