Spraying is something that takes alot of practice, maybe try the mirors, but id get somebody to do the bumpers etc.
Gearbox, either an F13cr or F15cr (corsa sport/sri/gsi) and same for the drive shafts.
You will need an MPI fuel pump (also found in corsa sports etc)
Mounts will be the std ones from the 1.2
If its an earlier x18 it should have a throttle cable (later ones were electronic)
With renault wheels its the offset thats usually the problem (so stick out further in the arch) personally id sel then and buy some original vauxhall alloys, or some aftermarket ones with pcd 4x100, offset et45-49 and 6 or 6.5" wide, you will have no problems with rubbing, even with 4 passengers.
Also take the top bolt out of the rear arch trims, as the nut can catch on the tyres
