Hi Steve.
To prepare you self for fork removal, a strap spanner or seal holder tool is required if you want to salvage the seal holders. This is a tubular design tool with external tangs to locate into the seal holder slots, I,ve made one so not difficult to construct, but they can be bought. The bushes may well need replacing, would be best to check with forks still assembled to the bike. Certainly you will require new seals, and may be seal holders, together with bush shims. A point to note is when assembling the seal holder to fork leg, a leak proof connection has to be made, in the old days they used twine, but PTFE tape or silicon is my suggestion. When you have removed the fork holders you will find a circlip (not the type with locating holes for pliers, just a plain ring, which is a challenge to remove), this has to be removed to enable inner fork leg together with bushes to be withdrawn.
Reaasembly is straight forward, except trying to get the top of the fork back into the yokes, again a tool is available which screws into the top of the fork, and when pulled forces fork taper into the yoke. Again I,ve made one, using an old fork top nut and machining off the hexagon and welding a suitable bar.
