Need some Manga help

Ai-Ren comes to mind for some reason.
Anything that's not Shounen Ai by Sahara Mizu is a good read.

If you like Kimi no Iru Machi, read Seo Kouji's other works, particularly Suzuka. I think he's a great mangaka.

I can't really think of anything that's not School Life, or young protagonist, actually. Huge staple of my reading lists it appears.

Until Death Do Us Part might be something to your interests as well, as it's primarily action.

Oh I will definitely check that out. In the mean time I've found this manga called Usagi Drop by doing random on OneManga and it's an interesting read so far.
