Will stay 1 night near the airport/Osaka area before activate 7-day JR Pass. Airport rapid trains use Osaka Station, and do NOT run via Shin-Osaka Station.
Ltd. Express Haruka trains and Shinkansen trains use Shin-Osaka Station, and do NOT run via Osaka Station.
The two stations are neighboring each other on another line of JR-West.
If you don't mind moving between the two, your options of districts for the accommodation include both Umeda and Shin-Osaka districts.

I'm a bit concerned about Hiroshima/Miyajima/Himeji in 2 days only. So am I.
In my last trip to Miyajima Island and City of Hiroshima, regrettably I didn't expect enough time, reaching the island in the evening and leaving it in the following morning to head to the city.
I recommend securing a daytime for each of the two sites.
Peace Memorial Park is vast, with A-bomb dome and Peace Museum located around its different ends.
I remember Hiroshima Castle was distant from Hiroshima Station more than I had thought and there was an underground passage for pedestrians to get close to it.
Around Himeji Castle's dungeon, there is a facility inside the covering for visitors to see Main Keep under the restoration work. Reservation is acceptable from one month before, which is not mandatory.
http://www.himejijo-syuri.jp/en/reservation/individual.htmlIf you visit Himeji Castle, you had better choose the timing when you will get recovered from jet fatigue. Between its entrance and dungeon, there are steep slopes and narrow roads.
In the facility an elevator is available.
On the final day, return to Osaka (Purchase the JR West Kansai one-day pass for 2,000 yen.) to catch the flight home @16:55 A Kansai Area Pass does not bring you a ride on a reserved seat of a Haruka train.
If you choose regular tickets, the cost with seat reservation will be 3290 yen on that day.
In Kyoto Station complex, the Shinkansen zone is around the south end (Hachijo end), while Track 30 for Haruka trains is around the north end (, in front of which over the street is Kyoto Tower).
Inner and outer passages between the two ends are on the 2nd floor; they are in the west half of the complex.
If your hotel is close to the north end, you just have to enter through Central Ticket Gate, walk to the right along Track 0 and reach the platform for Tracks 30 -34.
(Kyoto Station of JR-West does not have Track 1.)
http://www.jr-odekake.net/eki/img/premises/0610116_2d.gifYour options include a limousine if you leave Kyoto in early morning. The cost is 2500 yen for one way.
The limousines use a bus terminal near Hachijo end.
You can try making reservation for a ride to KIX. Please take into account a possible delay of your limousine.
