How to uninstall Bash ??

[San]

Dear Sir,

I am using "Red Hat Linux 9.0 (kernel : 2.4.20 -8)". I have downloaded all the 
files of 
Bash 3.2 (including the info files). I would like to know how to do the 
following things :

1. Remove the older version(s) (Uninstall)  of the Bash present on the
    system. 
2. Install the new version ( Bash 3.2)
3. Apply  the "bash32-00X.sig"   files located in the  bash-3.2-patches/  
directory
    on the GNU site : http://ftp.gnu.org/gnu/bash/ .
4. Install the Readline 5.1 
5. Install bash-doc-3.2.tar.gz  & bash-doc-3.2.tar.gz.sig 
6. Install bashref.texi.gz 

I want to know what is a .sig file & how it is used ? 

Please help me in the above things. I hope sincerely that you would help me in 
my endeavor.

Thanks & Regards,
San.
