Need Help in planning /connecting between Shinkansen using JR Pass

Greetings/hello,

We, senior citizens, have the following cities to visit during our 16 days in Japan in November i.e. Tokyo / Hakodate/ Kanazawa/ Nikko / Kawaguchiko ....

Our 1st route will be Tokyo => Hakodate => Hakodate [stay a few days] => then from Hakodate => Kanazawa. I checked and found that for the Hakodate => Kanazawa sector, as below :

<< Depart Shin-Hakodate @ ETD0935-Shinkansen Hayabusa 18 to Tokyo (Exit @ Omiya Stn. ETA 1344)
From Omiya to Kanazawa, ETD1449 Hokuriku-Shinkanzen Hakutaka 567, ETA 1720 Kanazawa >>

Questions : (1) is the above train routing /connection correct?
(2) Being not familiar with Omiya station, doesn't understand Japanese & senior citizens ... is it realistic that we catch the 1449hr /Hakutaka567 departure train to Kanazawa?

thank you in advance and sincerely looking forward to your kind support.
