Generally the packages for most distros are "sane" settings for both  
-- you just have to convince the package manager that removing the  
MTA is "okay" since a lot of packages depend on having an MTA present.

It's slightly distro-specific at that point, but after that, you'd be  
cookin' with gas.

Also if you've done a lot of modifications to sendmail (to add in  
spam filtering or use a smarthost at your ISP for outbound mail  
delivery, etc), you'd have to make a list of those things and then  
hack away on postfix to get the same (or similar) results... again  
Google is probably the most helpful here.

"switching from sendmail to postfix redhat" in Google found a Googol  
of hits.  :-)  Assuming you're doing a "redhat'ish" box.   I'm  
assuming that because you say you started out with sendmail... on the  
Debian derivatives you'd probably be coming from exim...
