For the gear cable guide on the down tube, the only new one I've found is this one:
https://www.sjscycles.co.uk/gear-spares/black-286-mm-origin8-clampon-double-frame-cable-stop/
which I've just used recently and it works fine (presuming you're using modern bar-mounted shifters).
For the cable guide under the bottom bracket, just buy a regular one like this

- although your frame might not have a hole to mount it, so you'll have to glue it on with epoxy glue or similar.
For the front derailleur you need to buy a 'band-on' one, rather than 'braze-on', although there is actually an adaptor to convert to band-on in case you do buy a full groupset with a braze-on FD. Again, I've used one of these recently and it works fine.

Alternatively, modern FDs also generally have a larger band size than the old 28.6 size, so you would need to get an adapter for that if you get a band-on FD. Something like this:
