Don't bother with all the service sh*t like plugs & leads, even the tappets I'd leave alone for the time being, you can do that at any time. You'll end up biting off more than you can chew.
You're doing drivetrain stuff, so just stick to drive train stuff. I'd do crank main seal, cv joints seeing as the shafts will be out, steering rack boots if they're needed, I'd chuck new clutch slave cylinder on and fuel filter purely because its easy to get at.
Your reco kit for the box will cost you $250 landed, a decent clutch will be around the $400 mark, machining the flywheel to match the clutch around the $60 mark give or take, CV's about $80 for the pair, slave about $40 bucks, gearbox oil $30, steering rack boots $30 for the pair. So there's $890 bucks without labour...
Oh & had you planned on booking in the gearbox reco with me?
It'll take me about a week to turn it around & you're currently 2nd in the queue behind Haltech Manual-conversion.
