While I think that your revised version does provide better advice than the WotC article, I think you've focused your tactical warlord too much into its secondary role of being a striker and not enough into its core role of being a leader. One element that I've noticed missing from your recommended feats and powers is the ability to grant extra saving throws. For this reason, I would mention the Saving Inspiration feat and the shake it off power, even though the latter uses Charisma.
As a matter of playstyle choice, I also tend to focus on abilities that give my allies more options and help them perform better instead of dealing damage myself. Thus, my eladrin tactical warlord prioritized feats like Tactical Assault, Fey Command, Combat Commander and Fey Tactics over Eladrin Soldier. That is not to say that I neglected dealing damage. The first feat I took was Student of the Sword to multiclass into swordmage, followed by Eladrin Swordmage Advance to get a free basic attack every time I fey stepped adjacent to an enemy. Multiclassing into swordmage also opened up the possibility of taking borrowed confidence at 16th level. When hitting is a premium, the ability to roll two d20s for every attack roll and use the higher result on every attack for one round every encounter is pure gold (IMO, of course).
The typical one-round assault on the most dangerous-seeming enemy will go: activate borrowed confidence, fey step adjacent to the enemy and move another ally with Fey Tactics to help me flank, attack (two rolls, pick higher) with the free basic attack from Eladrin Swordmage Advance, attack (two rolls, pick higher) with either thunderous fury or hypnotic swordplay (multiclass swordmage power), depending on whether I think it is more important to grant my allies an attack bonus against the target or to shut it down completely, or both if I spend an action point (which also recharges my fey step thanks to my Spiral Tactician paragon path) or, if I think it is time to use my daily power, lead the attack and hypnotic swordplay.
