(It would be good if this command can delete as well - otherwise i will have to fire this costly operation - find - once again to delete them. Although not a big problem..)
No, it will only archive the files. You should use another command to remove them:

Code:
find . -type f -mtime +1176 -exec rm +

If your find implementation does not support the + operator,
use xargs:

Code:
find . -type f -mtime +1176 | 
  xargs rm

2) I am not able to untar this directly. what's the way to check if this tar is safe (okay) ?

Below command returns me errors..
Code:
tar -tvf older_then_2008_2.tgz
tar: directory checksum error

I need to make sure - the files are still good - before i delete uncompressed files...
You should use something like this:

Code:
gzip -dc older_then_2008_2.tgz | tar -tvf -

shar

SHAR(1) 						    BSD General Commands Manual 						   SHAR(1)

NAME

     shar -- create a shell archive of files

SYNOPSIS

     shar file ...

DESCRIPTION

     shar writes an sh(1) shell script to the standard output which will recreate the file hierarchy specified by the command line operands.
     Directories will be recreated and must be specified before the files they contain (the find(1) utility does this correctly).

     shar is normally used for distributing files by ftp(1) or mail(1).

SEE ALSO

     compress(1), mail(1), tar(1), uuencode(1)

BUGS

     shar makes no provisions for special types of files or files containing magic characters.

EXAMPLES

     To create a shell archive of the program ls(1) and mail it to Rick:

	   cd ls
	   shar `find . -print` |  mail -s "ls source" rick

     To recreate the program directory:

	   mkdir ls
	   cd ls
	   ...
	   <delete header lines and examine mailed archive>
	   ...
	   sh archive

HISTORY

     The shar command appears in 4.4BSD.

SECURITY CONSIDERATIONS

     It is easy to insert trojan horses into shar files.  It is strongly recommended that all shell archive files be examined before running them
     through sh(1).  Archives produced using this implementation of shar may be easily examined with the command:

	   egrep -v '^[X#]' shar.file
