Hi,
Regarding first part, you can obtain 3D structures from SMILES or 2D
structure by CORINA demo online
(http://www.molecular-networks.com/online_demos/corina_demo). Small
molecules are generated with hydrogens'. Alternatively ACD Chemsketch
(freeware, http://www.acdlabs.com/resources/freeware/chemsketch/) could
convert 2D structures to SMILES. Probably best posibility is to use
VEGAZZ (free, http://www.ddl.unimi.it/) . Program could generate 3D
structure from 2D and have a lot of options to set-up and analyze NAMD
jobs/outputs.
