I havnt come across any Norse myths just revolving around Freya. However a fair few contain Freya and a couple are quite heavily based upon her, one of these being when Od goes missing and Freya goes around the world looking for him. A few myths revolve around her Beauty and quite often baddies use her as ransom. Freya also has an eagle cloak which often has saved the lives of many a god or goddess.
Norse mythology comes from early Scandinavia.

No. Quite a bit later on in fact.
The obvious answer here is 'Greek Myths'. This of course is under the assumption that you are talking about famous Greek Mythology such as Titans and Gods and Goddesses- Hercules and the like. The Greeks that created these myths lived long, long before 'Jesus', and the several of the writings about Greek Mythology happened around 500 B.C., While it appears the first draft of the standard Christian Holy Bible was not created until circa 261 A.D, which is more than 750 years AFTER most of the Greek Myths were penned. Of course the Greek Mythos began it's creation as early as the 8th and 6th century BC, while, according to Christian faith the New Testament of the Bible could not have been created before 0 A.D, even verbally the stories didn't exist yet.
Yes, the Greek civilisation preceded (is older than) the Roman civilisation. Many of the Roman gods are in fact the Greek gods that have been given Roman Names - eg the King of the Greek gods was called Zeus and this god became same as the Roman's king of the gods who was called Jupiter.

Yes, you can compare almost any mythology to another. For example I could compare Zeus and Thor. This a chart of what they have in common. -Lightning God -Primary God -Live in a World that is considered better than the human world. (Asgard for Norse and Olympus for Greek) These are a very few and simple things they have in common, if you spent a longer time on it you could come up with many more similarities. You could also find what is different about them.
Homer's Illiad is based in the time when Greek myths and their gods and goddesses were believed to be reality, so Greek myth came first.
The below link has a list for your enjoyment.
Of course they did. The Greek are famous for the myths about the Greek Gods. You know Zeus King of all Gods, or Aphrodite goddess of love and beauty. Athena goddess of strategies of war and knowledge who came from one of Zeus's headaches. There are many myths that the greek have come up with.
