For feats, I would be recommending spring attack, combat reflexes, hold the line, and power attack. As much as possible, you want extra attacks. Whirlwind attack is difficult to use effectively with reach; your opponents would have to be spaced out just so, and many of them would have cover. Spiked gauntlets and armor spikes are great, but using them as more than a fallback means delving into things like Two Weapon Fighting and Quick Draw.
Combat Reflexes and Hold the Line are an absolute must, get them, and possibly Improved Trip, as soon as possible. Then to get Spring Attack you'll also need to get Dodge and Mobility.
Power Attack isn't that much use at very low levels, because you're only adding a few points of damage at most.
Whirlwind, as pawsplay noted, isn't going to be that useful. Great Cleave isn't going to be that useful either unless your DM is fond of throwing hordes of weak fodder at you, or you're spreading your attacks out on multiple foes as opposed to concentrating on dropping one at a time.
Stand Still, though situationally useful, can be handy when somebody's trying to charge past you to hit your party casters.
Myself, I'd use Human as my race for a build like this (for the extra feat).
1 - Exotic Weapon Proficiency (Spiked Chain) (Human Bonus), Combat Expertise (Fighter Bonus), Combat Reflexes (Starting)
2 - Hold the Line (Fighter Bonus)
3 - Improved Trip/Dodge
4 - Dodge/Improved Trip (Fighter Bonus)
5 -
6 - Mobility, Spring Attack/Stand Still (Fighter Bonus)
7 -
8 - Stand Still/Spring Attack (Fighter Bonus)
9 - Power Attack
Alternatively, if your DM disapproves of the Spiked Chain, go with Quick Draw instead of EWP(Spiked Chain) to get your secondary weapon in use faster - or get Dodge at 1 and Mobility at 3 or 4 then Spring Attack and Stand Still at 6, then Power Attack at 8.
Alternatively, pick up a level or two of monk - lose one or two fighter bonus feats, but you'd pick up two of the Monk bonus feats, plus you wouldn't need to burn a feat to hit people inside of your reach.
