Looking to go outside my comic book comfort zone...

i would try Higher Earths, Popeye, TMNT(new ongoing from IDW) Prophet, Glory, Hell Yeah, Mind the Gap, Planet of the Apes, Skullkickers, and Planetoid.

A few people have already suggested these, but I will add my voice to those reccommendations because they really are very good books:

Usagi Yojimbo (Dark Horse): It does have its more serious moments, but for the most part this is a lighter tale about a samurai rabbit. It is a personal favorite of mine and I have been following it for over 15 years.
Mega Man (Archie): This is actually one of the few "superhero-ish" comics I have ever truly enjoyed. And it is definitley the only one that is not dark and gritty and/or gory (the other one is The Boys, from Dynamite, but The Boys has a HUGE gore factor to it so it may not be what you are looking for.)

You mention in your original post that you are also looking to give some manga a try. If so, Viz has published a number of works by Naoki Urasawa. I don't know if they are all available digitally yet but I would recommend pretty much anything by him with a special emphasis on Pluto (a fairly PG, 8-volume whodunit that is basically a more "grown-up" version of one of the Astro Boy story arcs by Osamu Tezuka). I'd also recommend 20th Century Boys, which is more of a drama/political thriller.

If you haven't already done so, you should post a "seeking recommendations" post on the Anime/manga boards and see what else others may recommend.

So you want a book book? Nothing Internet related content. Something tangible?

Either is fine, but I honestly prefer digital now.

Right now I'm loving The Massive from Dark Horse, and Saga and Danger Club from Image. Not sure what the price point is, and the latter two are definitely more "mature," but they are my absolute favorite books on the market right now.
