When writing the formula of a compound does the symbol of the element with the positive oxidation number come first?

Usually yes. However, with more complex molecules, there may be molecular ions which throw the sequence out.
For example, alum is K2SO4.(Al2SO4)2.24H2O
Here the positive ions are K, Al and H but these are subsumed in their corresponding multiatomic ions.

What is the oxidation number of P in PO?
There is no compound by the formula PO. There is element, polonium with the symbol, Po, and in elemental form, Po has zero oxidation state.
What is the formula of potassium hexafluoro platinate IV?
This formula is K2PtF6. The six fluorine atoms are indicated by the prefix "hexa"; each fluorine atom always has -1 as its oxidation state in a compound with any other element; the oxidation number of platinum is specified by "IV" and is positive; this means that two additional positive oxidation numbers are required from the remaining element, potassium, which in compounds always has an oxidation number of +1 per atom, so that two atoms are required. The order of the atomic symbols follows from the rule that the least electronegative element's symbol should be written first and the most electronegative element's symbol should be last.

What does the roman mean in an ionic compound?
A Roman number in the name of an ionic compound gives the absolute value of the oxidation number of that element in the compound which immediately precedes the Roman number. This is most common with cations of elements, such as copper and cobalt, that can form stable cations in more than one oxidation state. Copper(II) chloride, for example as the formula CuCl2 while copper(I) chloride has the formula CuCl.
