Hi, really quickly:

what is the type of bonding in MgI2 (magnesium iodide), is it ionic with heavy covalent character or is it just covalent? any thoughts/ answers hugely appreciated, thank you!

Well,

The ions involved would be Mg2+ and I-

Then to form MgI2 would have to be ionic bonding between the ions. So I would just say ionic bonding which forms an ionic compound.

Agree with CaptainDuckie:

Mg2+ and 2 I- ions are the parts to form this bonding. As two ions are involved, the product is an ionic bonding: Mg2+ + 2 I- -> MgI2. The oxidation number confirms it: it is zero after the reaction. It works then.

The large iodide ion will be highly polarised by the small highly charged mg2+ cation, the difference in electronegativity, Mg (1.2) and iodine (2.5) gives a difference if 1.3, this means that the bonding will be around 30% ionic and 70% covalent
