The lipid top files on Peters web site are for the ffgmx forcefield, does anyone have these file with the correct force constants for the ffG43 forcefields. Or perhaps am i missing something and i can use the existing dppc.itp forcefield (ffgmx) whilst using ffG43 for my protein.

No, don't mix them. IIRC, there is an g43a flavour with enhanced lipid 
parameters. You'd have to convert the lipid topologies to the right 
parameters (atom types, bondeds types), but they may be available 
somewhere already. (anyone?)
