Three RPM questions.

I downloaded X Multimedia System 1.2.9 RPMs for Redhat 9.x, and these are :

xmms-1.2.9-1.i386.rpm ( XMMS )
xmms-devel-1.2.9-1.i386.rpm ( XMMS - static libraries and header files )
xmms-debuginfo-1.2.9-1.i386.rpm ( Debug information for package xmms )
xmms-gl-1.2.9-1.i386.rpm ( a kind of plugin )
xmms-mikmod-1.2.9-1.i386.rpm ( a kind of plugin )
xmms-vorbis-1.2.9-1.i386.rpm ( a kind of plugin )
xmms-esd-1.2.9-1.i386.rpm ( a kind of plugin )

And my Redhat 9 linux system already has an older version of xmms 1.2.7.
Query result by "rpm -qa | grep xmms" displays :

xmms-1.2.7-21.p
xmms-skins-1.2.7-21.p

[ Question 1 ]

I want to upgrade xmms1.2.7 on my system to new version 1.2.9 .
When installing xmms-1.2.9, is it OK to skip xmms-devel-1.2.9-1.i386.rpm and xmms-debuginfo-1.2.9-1.i386.rpm ?

[ Question 2 ]

Is this a right way to upgrade xmms ?

su -
rpm -Uvh xmms-1.2.9-1.i386.rpm
rpm -Uvh xmms-devel-1.2.9-1.i386.rpm
rpm -Uvh xmms-debuginfo-1.2.9-1.i386.rpm
rpm -Uvh xmms-gl-1.2.9-1.i386.rpm
rpm -Uvh xmms-mikmod-1.2.9-1.i386.rpm
rpm -Uvh xmms-vorbis-1.2.9-1.i386.rpm
rpm -Uvh xmms-esd-1.2.9-1.i386.rpm
exit

[ Question 3 ]

Is this a right way to upgrade xmms ?

su -
rpm -Uvh xmms-*.rpm
exit
