A 14-day Japan Rail Pass [JRP]
(sold at about 47000 yen) sounds not best cost-wise.
Tateyama Kurobe Alpine Route
is served fully by non-JR transportation;
JRP is never usable there.
You don't need 40000 yen for the other interregional legs.
You have many other destinations outside Kanto Region,
which may well take at least 10 days for first-timers,
therefore a 7-day JRP sounds not suitable, either.

Kintetsu | Nankai has its Osaka terminal in Namba area.
Osaka Station is in Umeda area.
The Shinkansen terminal is Shin-Osaka Station.
Namba, Umeda and Shin-Osaka
are connected each other by Osaka Metro.
#2:
The both passes are used on the day you go to Kanazawa,
so you leave Osaka for Hiroshima and get to Toyama
within 8 calendar days.
#3:
To have a rest on the way, Shin-Osaka sounds better than Kyoto;
the Shinkansen section between the two
is operated by JR-Central,
therefore not covered by JR-West passes.
