Also, Golems are just a more interesting question. Almost any form of attack will hurt a warforged just fine... what's to talk about?
There's plenty to know about Constructs as well as the difference between Living Constructs and Constructs.
Unlike constructs, living constructs are affected by things that specify "living creatures." Now, I know this might seem obvious, but its still worth it to point out, I think. They also have a Con score and lose the seeming universal Construct immunities to mind-affecting abilities, non-lethal damage, stunning, ability damage, ability drain, and death effects.
This makes them very different from Constructs. Since the OP didn't feel the need to call out "warforged" in the opening post, he or she might not be aware of these important differences.
They keep: immunity to gas based attacks, poison, sleep, paralysis, disease, nausea, fatigue, exhaustion, and, energy drain. That's important to keep in mind, because many spells that would normally be useful against most PC race types will be useless against warforged. For example,
hold person, the monk's stunning fist,
contagion,
cloudkill, and
waves of fatigue are useless.
They are subject to sneak attack, but have a 25% natural immunity to them. So, rogues are still will want to flank if they deem it is safe enough to warrant the 25% immunity to their sneak attacks. This is a difference between constructs, in which it is only worth flanking for the +2 to hit, and non-constructs in which you will almost always have sneak attack when you're flanking.
