You should leave them there, they were the ones that alsaconf created
for the alsa configuration. "modules.conf" looks fine to me.

Not easy. A while ago I started to write a script that would list them,
never finished it :-) As you don't have anything in modules.conf related
to the old oss drivers a reboot should be enough to ensure no oss
modules are loaded. 

Try to start alsa again after rebooting, post any related messages you
see in /var/log/messages or in the output of dmesg.
