Get straight into the restoration. Don't worry about fixing the game now, as all the faults will be addressed during the restoration process. Take your time and enjoy the process. Male a list of the parts you need as you go along. There's nothing worse than placing an order and then realizing you forgot something !

Make sure to take heaps and heaps and heaps of photographs as you go.  You may find yourself 'in the groove' and before you know it 3/4 of the playfield is stripped.  As Nino suggested, take your time, label everything and be careful as those ramps are expensive...

Make a list and try to do your orders in one hit.  There will always be stuff you forget, Greg (RTBB) normally gets about 3 orders after my main order of little stuff like shooter rebuild kits etc which I sometimes forget in the main order.
