For  those of you who have used the International eyelets, which type
have you  used ? ( i.e. flat, funnel or rolled flange ).<<
I have used flat infrequently, but mostly rolled flange.  These should  not 
be NON-plated, as it is virtually impossible for solder to wick under the  
rolled head, when swaged tightly in a hole.  Also, the PCB should be  
solder-plated for same reason.

Also  what type of plating. Have you used the solder plated eyelets  ?<<
See above.  Gold (expensive) wick OK (I got some cheap at a "surplus"  
outlet), but "solder-plated" is best for small-quantity ("hobbiest") purposes, I  
think

Would  using those mean that after setting them I would just have to heat 
them with  the iron and be done with them ?<<
IF there is re-flowed solder-plate on the PCB, this might work, but only if  
there had been some "rosin flux" for the purpose, I suppose like is used for  
SMT, painted on before eyelets.  If you would not be applying solder-wire  at 
time of eyelet-heating, the iron-tip would become nasty and "dry" very fast,  
and leave a streaky, dirty mess about the tiny eyelet heads!  For this kind  
of "re-heat soldering" a hot-air gun might be a better idea, but decent use  
would require experience and failure until "learned"!!!
