Odysseus' boat will be wrecked by Poseidon, but otherwise no "adversities at sea" will face Odysseus. The various well-known adventures of Odysseus, such as Skylla and Kharybdis and the Clashing Rocks, although described later in the Odyssey, have actually already taken place.
Penelope
Kalypso assumes that divinities and humans are entirely different - a view which is included at the beginning of Nemean 6. On the other hand, Pindar states that we can somehow come near to the gods through athletic accomplishments; although in a different way, Odysseus would also seem to be acting on the assumption that humans can somehow approach the level of the gods.
Basically, "Akhaians" and "Argive" [along with the term "Danaan"] refer to the Greeks fighting at Troy. {It is more or less the standard Oralist view, briefly sketched by H & P, p. 363 "The Question of Authorship", that "Akhaians", "Argives", and "Danaans" are simply metrical variants, convenient for an oral performer; this point, along with variations on it, will be discussed more fully after the Oct. 6 test.}
Hephaistos.
Ares.
At least in lines 8-9, Hesiod simply says, without qualification, that "it was predestined that very wise children would be born from Metis". Hesiod's overall presentation, though, is that one child, Athena, is born, but no son who would overthrow Zeus.
The specific reference to Hera and Zeus going to bed together is not, perhaps, directly relevant to Xenophanes' criticism of Homer's gods as being immoral. However, the broader context - Zeus's more or less secret meeting with Thetis, Hera's complaint about this, and Zeus's arrogant retort to Hera - well illustrate the relatively undesirable human traits which Homer ascribes to divinities in the Iliad. Overall, this could be said to be exactly the sort of thing to which Xenophanes objected in Homer's (and Hesiod's) portrayal of gods and goddesses.
The specific craft which is referred to in "2" is the invisible net which Hephaistos designs to catch and hold Ares and Aphrodite in bed together.
