1. The Hogyoku being in Rukia's gigai came from the anime intro. Not the manga. Kubo never made clear how Rukia ended up with the Hogyoku in the manga.

More importantly, he promised to tell Renji all about it should Renji train Chad. Renji did keep his end of the bargain so soon we'll know where the Urahara-Rukia connection comes from. For all we know, Urahara stumbled on a baby Rukia after Hisana abandoned her and put the Hogyoku in her then and Aizen didn't become aware of Rukia until after she was adopted by the Kuchiki clan and thus ran into problems because a Kuchiki isn't that easy to just kill off.

2. Maintaining the barrier? Making sure the residents of Karakura Town were fine? Rescuing Kon from Division 12 (volume 44)? Yama-jii ordered him to not enter the fray until the Gotei 13 fell? A lot of things were revealed through volume sketches. People really need to check those out before assuming that character X's activities were unaccounted for.

3. Tessei mentioned the Urahara used to live in Yoruichi's manor but most people in Bleach don't go around talking about their family. Has Ukitake ever mentioned his family? Kyoraku? Has Yoruichi explained if she has any brothers or sisters and who is the current head of the Shihonin clan assuming she no longer is? We know what we know because Kubo explained those things in character profiles in databooks and stuff like that. NOT in-manga. When Urahara has a character profile released on him, we'll no more.

As I said, there is a few things we don't know about Urahara. But it doesn't mean he's actively hiding anything. Kubo has simply chosen not to reveal things yet. So you can say that Urahara's character is not fully developed. He's not hiding things.
