For the first 1,000 miles Morgan recommends that you keep the engine under 4,000rpm
After you've had the car for 2-4 weeks (or 1,000 miles), they service the car and tighten anything that has become loose (and fix any issues that have arisen). There is no oil service at this time as the engine has been bench broken. Pretty simple really <img src="/forums/images/graemlins/smile.gif" alt="" />
Service intervals I'm not too sure about - I'm sure someone else will come along and answer that part. However, BMW offer variable service intervals on the V8 4.4 valvetronic (depending on how it is used, temperatures, time, type of use, driving conditions, etc), so chances are that if Morgan are stating yearly intervals, this may be mild overkill.
