I'm afraid there's no "quick way" to do what you request. It has to be done like what you describe, line by line, value by value. Why don't you post your attempt to be discussed, analysed, and hopefully improved? And, post the desired output for problem 2.
By the way, a similar problem has been solved here.

jfs_fsck
jfs_fsck(8) JFS utility - file system check jfs_fsck(8)NAME
jfs_fsck - initiate replay of the JFS transaction log, and check and repair a JFS formatted device
SYNOPSIS
jfs_fsck [ -afnpvV ] [ -j journal_device ] [ --omit_journal_replay ] [ --replay_journal_only ] device
DESCRIPTION
jfs_fsck is used to replay the JFS transaction log, check a JFS formatted device for errors, and fix any errors found.
device is the special file name corresponding to the actual device to be checked (e.g. /dev/hdb1).
jfs_fsck must be run as root.
WARNING
jfs_fsck should only be used to check an unmounted file system or a file system that is mounted READ ONLY. Using jfs_fsck to check a file
system mounted other than READ ONLY could seriously damage the file system!
OPTIONS
If no options are selected, the default is -p.
-a Autocheck mode - Replay the transaction log. Do not continue fsck processing unless the aggregate state is dirty or the log replay
failed. Functionally equivalent to -p. Autocheck mode is typically the default mode used when jfs_fsck is called at boot time.
-f Replay the transaction log and force checking even if the file system appears clean. Repair all problems automatically.
-j journal_device
Specify the journal device.
-n Open the file system read only. Do not replay the transaction log. Report errors, but do not repair them.
--omit_journal_replay
Omit the replay of the transaction log. This option should not be used unless as a last resort (i.e. the log has been severely
corrupted and replaying it causes further problems).
-p Automatically repair ("preen") the file system. Replay the transaction log. Do not continue fsck processing unless the aggregate
state is dirty or the log replay failed. Functionally equivalent to -a.
--replay_journal_only
Only replay the transaction log. Do not continue with a full file system check if the replay fails or if the file system is still
dirty even after a journal replay. In general, this option should only be used for debugging purposes as it could leave the file
system in an unmountable state. This option cannot be used with -f, -n, or --omit_journal_replay.
-v Verbose messaging - print details and debug statements to stdout.
-V Print version information and exit (regardless of any other chosen options).
EXAMPLES
Check the 3rd partition on the 2nd hard disk, print extended information to stdout, replay the transaction log, force complete jfs_fsck
checking, and give permission to repair all errors:
jfs_fsck -v -f /dev/hdb3
Check the 5th partition on the 1st hard disk, and report, but do not repair, any errors:
jfs_fsck -n /dev/hda5
EXIT CODE
The exit code returned by jfs_fsck represents one of the following conditions:
0 No errors
1 File system errors corrected and/or transaction log replayed successfully
2 File system errors corrected, system should be rebooted if file system was mounted
4 File system errors left uncorrected
8 Operational error
16 Usage or syntax error
128 Shared library error
