Clarifications on some Magus interactions

[Kiki_Pingu]

Hi, first time poster here.

My group is starting a fresh campaign and I have decided to make an android Magus (Iron gods adv. path).
I have a few questions regarding some rules interactions:

From what I have read online it seems you can use weapon finesse with touch attacks (spells like shocking grasp).
Where is this stated ? I am aware that delivering touch spells counts as an 'armed' unarmed attack, and unarmed strike counts as a light weapon.
If this is enough to make weapon finesse work for touch spells, can you use weapon focus(unarmed strike) to get a bonus when delivering touch spells? If not, why ?

Second question, can you make a full attack action with spellstrike and held charge? It seems to me that you should be able to.

Third question, I have seen the faq regarding magus spell recall and metamagic (regarding spell level). If you recall intensified shocking grasp, does it retain its metamagic or is it just a regular shocking grasp?

Final question, does dervish dance still work with spell combat ?

Any help is appreciated.

TLDR: Yes to all.

Weapon Finesse: Weapon Finesse requires the feat and a weapon that is compatible. Unarmed strike (including delivering touch spells) or a Rapier would work, but if using Spellstrike you're limited to the weapon delivering the charge - eg. a Warhammer wouldn't get Finesse just because you're using it to deliver a spell.

Held Charge: It sounds like you understand how this works, but just in case read GRICK'S GUIDE TO TOUCH SPELLS. Also, make your GM read it before you play. There are a few fairly/very unusual rules interacting here, so most people don't know how this works if they haven't player a Magus. Mastering it yourself doesn't matter if your GM doesn't understand it and won't let it work.

Spell Recall: Yes you keep the Metamagic. You actually MUST keep the metamagic whether you want to or not, the spell comes back as it was (so Elemetal [acid] Shocking Grasp would come back as an Elemental [acid] Shocking Grasp, even if you wanted to deal electricity damage). Improved Spell Recall fixes this since you can recall a different spell, but it costs more Arcane Pool points.

Dervish Dance: Yup.
