Please read print old man at goban

Please read signature (嵐岳?) and seal on this print of an old man at a goban.
If the text is too long for a full translation, what does it roughly say?
Is it signed or dated?
Could this be a surimono?
Does it identify the old man?

I think the old man is identified by the writing in the lower left
中巨摩群
豊村旧吉田
保坂伊左衛門祖父
五兵衛

Naka Koma-gun (name of county, in present-day Yamanashi Prefecture)
Yutakamura (formerly Yoshida) (names of villages, now this area is a part of "Minami Alps City")
HOSAKA Isaemon's Grandfather
Gohei (personal name)

The writings at the top are three different poems, but I don't think they are famous poems by famous poets. Maybe some local poets? And my wild guess is that they relate to age, wisdom, etc.. and they celebrate the long life of Gohei.

Reading of 嵐岳 might be Arashidake? I guess its the artist, but a quick search isn't turning up any hints.
