I got the Old Man Logan book, now I want to see what happens after he leaves trying to save the world. Is there even anything written after that?

No, but Wolverine Origins is amazing. You might like Daken.

Mark Millar's Fantastic Four follows Old Man Logan but was written before it. Old Man Logan becomes the Hooded Man and joins the New Defenders [which later becomes Fantastic Force]. After Millar's Fantastic Four New Defenders arc, there's a Fantastic Force mini-series in which he's prominent in.

What comes after Old Man Logan?

It doesn't directly follow... "

Older Man Logan

^^^ LOL clever. I wish Millar would do a continuation of Old Man Logan, it was one of my favorite Wolverine's ever.

Geriatric Logan: complete with retractable adamantium walker. 
 
"Snik-aaah!  my back!"

Hahaha wow, Geriatric Logan sounds hilarious! I still think Wolvey in a wheelchair could still do a lot of damage if he wanted though.
