I will then buy a domain name with one of these domain registrars and ask them to change the nameservers over to my web host's.
This will means that the website url will be resolved as per usual whereby the domain name and file name are always displayed in the location bar.
My question is does any one know if this kind of practice, i.e. where the domain name is not hosted with the web site, affects the SE spider's ability to spider my web site?
So, you can host your site somewhere else, you'll just update your domain registration to use whatever nameservers your host uses.

My understanding obviously lacks a bit!
Having said that I remember that one of my hosts registered a previous domain name with a registrar themselves (without me 'knowing'). Most of them probably do it!
Cheers.
