The /24 address block has to be portable, an assignment, or the owner needs
to grant the secondary advertiser an LOA to readvertise that block. The LOA
is pretty common, but some ISPs may require you to renumber to get into
address space they will permit you to use and multihome. As always your
mileage may vary.

....that part isn't required.   Generally any /24 will do in my 
experience except for specific cases.

Other than that, you've got it about right.
