Just off the top of my head:
-- Small socket or wrench to unbolt battery cables from battery (undo the negative ground first, then the positive)
-- Large-ish metric socket, like maybe 15mm or so, and 1/2"-drive socket handle (preferable, though 3/8"-drive will do as well) to back off belt tensioner to enable you to lift the serpentine drive belt off the alternator puller. Use longest socket handle you have (a breaker bar handle is ideal) for maximum leverage, and back off tensioner by turning the bolt head in the middle of the pulley _clockwise_. You're pressing against a pretty powerful spring; wrapping a rag around the socket handle will help cushion it. Press down on the handle to relax the tensioner with one hand as you work the belt off the pulley with the other. (Whatever size it is, it _is_ metric, it _is_ a powerful spring in the tensioner, and you want a proper fit of the wrench to prevent any sudden unpleasantness.)
-- Unscrew and/or unplug wiring connections at alternator. It may be easier to do this either after or during the next step when you're undoing the mounting bolts.
-- With various sockets and short extensions as appropriate, unbolt the two large bolts holding the alternator. One bolt is a large pass-through going through front and rear mounts; I think the other is shorter. Pay attention to which is which, what the order of nut-bolt-washer is for each, and which way the bolts are facing. It'* probably easier to pull the long bolt out last, and have it be the first one going back in.
-- Lift out alternator. It'* probably a bit heavier than it looks, so lift it out carefully to avoid bonking it on other expensive components under the hood. Temporarily put the mounting bolts back in their holes in the mounting brackets while you're out running around town, so you don't forget which goes where.
When trading it in for a new/rebuilt one over the counter, make sure that the new one has all the necessary bits 'n' pieces such as retaining nut(*) on the wiring connection studs, that kind of thing. Ideally, get the new one home first, install it, _then_ take the old one back for your core charge credit, so you don't accidentally trade in any vital pieces that you should have swapped over. Have fun; it'* not that hard of a job.
