Blog Help?

I’ve got most everything figured out (sorta), and I have Live Writer set up for posting (which is AH-mayzing, btw.  I love it)
I’m just having trouble figuring out how to:
1.  Insert entry separator thingys.  I’ve looked at a couple of tutorials, but the info that is provided doesn’t look like what I have going on, so I get a bit….stuck. 
2.  Pretty/functional header.  And how to insert it.  I haven’t found one that I’m in love with yet, (and I’m having zero creative luck in Photoshop), but I still am not 100% sure how to insert said header once I find one that doesn’t make my skin crawl.
3.  Motivating my poor long suffering hubby in finishing up the script that will port over my LJ crap.  Hm.  Maybe cookies?  I guess you guys can’t really help me out with this one.
Soooooooooo……….can anyone point me to some helpful instructions on either of these things?  (And if anyone has art that would work for a header, I’ll be forever grateful.  Mebbe I’ll make you something in exchange?)


p.s.  Yes, my personal life has already crept into this blog, which is what I had a problem with in my old LJ.  But I’m going to try to keep it mostly topical.  (Like posting inspiration pics from New Orleans, perhaps?!)
