I don't think there is an order guide for the 3504.
The ability to roam between different controllers is more to do with the software version than the hardware platfom - you can review all of the possibilities here - https://www.cisco.com/c/en/us/td/docs/wireless/compatibility/matrix/compatibility-matrix.html#pgfId-149658
(Basically it all works any way you can think of it, so long as you avoid v5 software, which should be easy as its so old)
BoM below is about what you'll need, though be aware this is based on a UK region spec - if you're elsewhere you might want a different power cable, different support options, remove encryption license, etc... Also remember that the 3504 is limited to an absolute maximum of 3000 Clients / 4Gbps - if you're even half way to this I'd consider using a bigger WLC.
