I want to include a couple of JL sectors. Do I book the trip up to this point and then ring assistance to have the JL added. Thanks JV
First, have you looked at this thread?:

There is an awesome amount of information in there and reading at least the last 12 months worth of posts will be invaluable to you and well worth the time it takes.
To answer your specific question:
1. JL award flights are not bookable on the QF multi-city tool as you seem to be aware;
2. Assuming that all your flights are within the booking period (330 - 360 days depending on airline), then work out your itinerary and confirm available flights using BA, QF and other search engines.
3. Make a list of all flights: date, flight numbers, departure airport and time, arrival airport and time. Check the mileage on Great Circle Mapper and don't forget to allow for surface sectors.
4. When all good to go, ring QF and advise the agent that you want to book a 280k award but the on-line site will not allow you to book the JL flights. IME, if you are genuinely ringing because the on-line tool can't handle the booking AND you have obviously done your research so that the agent can book it quickly (15 minutes rather than an hour or two), you will usually have little trouble in having the booking fee waived.
5. If your itinerary extends past the eligible booking period, then book what is available using a "dummy" flight to return home. This will close the points out at 280k (assuming you are within the rules) and lock in the flights you want. Then when your desired flights open up, ring QF and amend/add the remaining flights. This will cost you 3,500 points change fee PER PERSON each time you change/add.
Good luck,
