Regarding elements...

Question here, does equipping a magatama that has, for example +10 fire affect your auto-attack, or only skills, or only skills that have flame on it (like fireball and such)?

Only skills with Fire. It will also increase your defenses against said element.

Ok thank you for that useful information. With regards to impact element - what does this do? Is this for skills that don't have any element on them like rapid shot?

The wiki people have worked hard to compile information, you should utilize it.

Elements
Within combat, each attack offers different kinds of attack style and element. There are currently three attack styles and 9 elements.
Styles
Styles determine the type of force a weapon inflicts upon an enemy: slicing, impact or piercing. Different youkai has different resistances to each.
Slice: Slice, as its name indicates, is an attack where a blade cuts the enemy. The katana, odachi and twin blades are the weapons that often offer this kind of attack style.
Impact: Impact, as its name indicates, is an attack that uses brute force to inflict blunt damage. The axe, wand and staff are the weapons that often offer this kind of attack style.
Pierce: Pierce, as its name indicates is an attack that attempts to stab the enemy with a sharp attack. The bow and spear are the weapons that often offer this kind of attack style.
One other attack style is the "multihit" style. But this is a style more related to abilities, not the basic attacks.
