From the sound of it you have series 1 so need the mirror cover which covers the whole mirror without the indicator cutout as on the S2 and S3.
Not so long ago there were plenty of both sorts listed on Aliexpress but I have just had a look and can now only find one seller who only has covers for S2 and S3 with the cutouts so no good for you.
You might want to keep an eye on the Japanese auctions as used ones come up quite regularly.
I f you do find one fitting is very simple, just double sided tape as they are not a replacement but just fit over the existing mirror
As regards the door covers the cheapest I could find on Aliexpress is from this seller who does ship to the UK.
Cost including vat and postage is £25.34

To complete the look you could also consider these side indicator covers from Japan Amazon, cost is £18.32 but then would need to add postage, proxy fees and vat etc.
I have had these in my watchlist for a little while as I have thought of buying them for my S1 but them hydrodipping them in carbon to match the rest of what I have done.
Same as me with my Rider as you have Rider S you will have the clear indicator lens not the orange that they show
