James,
Go get a mutltimeter and check the resistor value your self.  No need to install stuff you are unsure of.

I'm no expert, but if some of the components aren't the right value, I'd go to an electronics store and get the right ones. 

I can't answer your other questions right now, but those are my responses at first blush.
Joe

It would be best to email directly for these types of questions.

The substitution for C18 is OK
All the resistors are labelled. Send me pictures of your board so far and the components.
Q5 qoes on after you verify the ECU is seeing the correct voltage with the Optimiser app.

No more jumpers for the IGN FETS
The bluetooth dongle must be external to the case as RF will not penetrate the metal case.

After a couple of minor glitches (I can't read or count), the ecu tested spot on!  Thanks Cliff.
Installed ecu and blue tooth last week, purchased an aldi tablet and loaded map, all good so far.  Ran bike then took it for a run around the block which went well until a massive backfire and limped bike home 400meteres missing coughing backfiring !!!  Tank off, checked sensors then un-taped ecu lid and found chip had come out of the socket.  I was not happy when I put the chip in and thought it should go in further to the pin shoulders but did not want to force it!  It is now seated properly.

Nice. You might benefit from at least some tuning of the upper few rows of 2nd-3rd column or so, ie. going from idle to very sudden WOT. Actually when we did that thoroughly on a Centauro (also with my map as base) we needed to set the top cells for 1150 & 1500 rps manually to max value (can't recall now but I think it is 16383), because when adjusting by percent it ended up rolling over to a lower number. Took some head scratching to figure that one out.

Sockets are a considerable point of failure in vehicles. I can't recall what socket I got from Cliff (I think it was fine) but in general they should be expensive because they are worth it. Ideally even a ZIF socket that holds it tight as hell. I've had relays popping out of their sockets twice, both times (of course) when overtaking cars with meeting traffic ahead... I've actually had zip ties around all relays even since - I don't want another of those t-shirts 

Guzziando,
The link isn't working for me.  Regardless, is this your first time soldering?  Perhaps you should practice first on a simpler item.
Joe

Cliff gives great advice, so you should be in good shape.
