Hello Vivek,
regarding ur original question: u can find the rpms by using the search tool in GNOME or Kde or by using from terminal as root or sudo:
Code:
~$sudo find / -iname *.rpm
^ and check the dir containing max no of rpms.this is the cache directory.also looking the file /etc/yum.conf may help where it stores rpms.

I think You should settle with a distro u like inorder to learn and benefit from Open Source and Linux.
I think You are not new to Debian or Ubuntu.SO settle with one of these distros and learn by tinkering its configs-apt,dpkg and 20000+ packages.
OpenSuse may attract with its much better graphics and gui for once for a newbie.by default it installs loads of s/w which inturn are unusable.while Debian or Ubuntu or many other distros doesnt do the same.But the rpm and yum are yet to fix the job of managing the packages as effectively as Debian based distro's apt and dpkg(deb) does.
In future if ur much interested in Linux.U can take
RHCE or
LPIC.get urself secured @ smartcity kakkanad
