G'Day and welcome to SRP.
Either of those would make good shavers IMHO as long as they are shave ready.
I'm not sure what you mean by 'upgrading' the cloth side of the strop - I have linen on a vintage strop and felt on my new one - both work well.
I wouldn't be too concerned about a barbers hone at this point - send your blades out for honing in the short term.
As far as brushes and soaps go, you should have enough if you've been DE shaving for a while.
I hope this helps
