Networking noob!

Ok so recently I started using wifi from cabled network, My dad bought a Linksys E2000 router from US.Initially I thought it was a Modem+Router and tried everything to make it work, the realized i also need a modem to use it and attached a MTNL modem i had via ethernet cable.Now I am planning to return the MTNL modem(cancel the Rs.50 rent) and buy a ADSL2+ wired MODEM.Now a friend to me that i need to change certain settings in the modem configuration page, like then MTNL people did in the modem they provided, but my router as well as my MODEM has a configuration page so I am confused as to which setting in the correct one, do I need to forward ports on both(for certain apps) ?Should I buy wired Modem or get a new Modem+Router and sell off my current router ?
