Congratulations- the game is afoot!
All of this is MHO- others may quickly throw more life lines - so grab the one that works best for you-!
You can contact Olympia Xpress CH- they sell parts like your boiler cap, lever , handle, basket and drip tray and grate. If you do not get get your order filled or there are items no longer in stock you can try some of these other options. Try them out MR Markus maybe all geared up and ready to go-
So Start here:

Boiler Cap:
Olympia? - I do not know of any other places- A critical detail. I am sure one can be made, threads cut and then inserted into a wooden or phenolic knob of some kind possibly also found at McMaster
Handle:
This was sniped from the Nakid PF arrives post- So Mc Master is a place for your handle
"my Cremina suggestion would be: fill search box with this part # from Mc Master-Carr.
3701T41
Metric Phenolic Tapered Handle Smooth, M12 X 1.75 Thread, 112 mm Length, 29mm Dia
In stock
Quantity Each
1-9 Each $8.14
10 or more 6.84"--- Note: you will need two- the threading for the handle-end of the lever is the same as the PF thread- M12X1.75. They will look almost exactly like the originals.
Lever:
You can check with a member or two for machining options- any of us can give you length so a local machinist could cut you some s/s rod and cut some threads. Same threads on both ends? I would have to check.. hardness / strength specs - a person in the know here would have to chime in
Drip tray:
Try Will, at Home Espresso Repair in Seattle- he might have the pair ( tray and grate)
http://www.espressorepair.com
Basket:
Once again Will - maybe or Stephano at
http://www.espressocare.com or our good folks at EPNW for La Pavoni or Elektra Microcasa Aleva baskets ( they can be used in the NEWD PF you have purchased from Richard with a little rounding of the edges).
Good luck
