Yes, I defently would, it is easier to configure, and it really works.
I read through all of your posting, but I don't quite see the problems,
and easy solutions.
I myself found the sendmail supplied with solaris not very usefull,
outright annoying, to be more correct.
So I got myself the sendmail binary from ftp://opcom.sun.ca:/pub/freeware,
and the configuration files from the sendmail source from
http://www.sendmail.org.
I then generated the m4 macros, and built the cf-file with m4 (needed a
new version, also to be found on opcom.sun.ca)
Probabely for you, the most usefull feature will be this, quoted from the
cf/README file:
masquerade_entire_domain
If masquerading is enabled (using MASQUERADE_AS) and
MASQUERADE_DOMAIN (see below) is set, this feature will
cause addresses to be rewritten such that the masquerading
domains are actually entire domains to be hidden. All
hosts within the masquerading domains will be rewritten
to the masquerade name (used in MASQUERADE_AS). For
example,
if you have:
MASQUERADE_AS(masq.com)
MASQUERADE_DOMAIN(foo.org)
MASQUERADE_DOMAIN(bar.com)
then *foo.org and *bar.com are converted to masq.com.
Without
this feature, only foo.org and bar.com are masqueraded.
This should solve all your problems immediately.
Also I would analyze all Problems with multiple runs of
/usr/lib/sendmail -bt, the Test-Mode, in which you can test all the
rewriting rules, and will find out directly where the bug is, not this
'looking on the output and guessing what went wrong'-thing you seem to do
right now.
There is some fairly good sendmail doku out there, like the sendmail book
from O'Reilly (2nd Edition), or 'TCP/IP Network Administration'.
To your actual problems:

Well, if you have a host, which is masquerading as a domain, it will use
this information for sending as well, prbabely you should instead of
chaning $m, change $w or $j instead, so it is just receiving as a host
from withhin the old domain.

Sames as above, the host seems to be somewhat confused, on what hostname
he actually has. As far as I know, sendmail makes some funny
gethostbyname, gethostbyaddr, gethostbyname permutations to get its fully
qualified domainname, so probabely you should do the same (reverse-lookup
from shadow's IP-Adress).

This looks real messy, no suggestions on sendmail
Hope this helps somewhat,
