Subject: [AMBER] lipid membrane(dppc) in amber

Hello every,
   I am simulating a GPCR in membrane doundaries, using AMBER 9/10. As a greenhand of AMBER, I got several problems with the simulation after referring to some related papers as well as the manual of AMBER.
1.  If I am using. GAFF can I use the parameters of GROMOS-96 force field for dppc?
2. If not where can I get parameter and topology for dppc in Amber ( I have surf the net but field.)
3. Someone suggested that "doing NPT in AMBER with ntp=2 leads to more unrealistic membrane properties than doing NPT in NAMD with the Langevin piston method to control the pressure" ( Is that true with you?
Thanks a lot
