amumu is weird in that he's part bomb part tank. I think you should build him less tanky than maokai for the simple reason that once his ult is down there's no reason for the enemy team to focus him. Although he does need some tank gear so he doesn't get poked down, and his ap ratios aren't too good... he does fills the support/aura role pretty well. But its not like maokai where you need to stay alive long enough to arcane smash over and over and over and over and also keep your ult up as long as possible.
I'd say abyssal scepter is core for amumu, and i'd be more likely to build sunfire cape... and I'd never build warmogs. Otherwise the builds are probably similar, you'd still want and locket and maybe aegis/bulwark.... the combo of locket/abyssal seems like a solid mid game goal build to me, you get health/armor from the locket, plus magic resist and damage from the abyssal... so a good mix of stats... if i played amumu I would probably build locket and abyssal scepter as my first big items.
for stat valuation i'd value auras/actives higher, magic penetration higher, and otherwise mostly the same.
