I must say, your source XML is a little funky. In particular I am
talking about the Address nodes and their corresponding Zip nodes.
Correlating them simply by their order isn't necessarily the best way
to do it, nor (as I recall) will the order *always* be respected,
depending on your processor.

I attempted to come up with a full solution for you. May work in a
rickety manner or not at all. As Ken says, because your problem is so
open-ended a better subject for this thread might be 'Someone do this
for me'. Luckily, I have a soft-spot for people who learn by example.

<xsl:template match="/">
	<ListOfCustomers>
		<xsl:apply-templates select="CustomerSet" />
	</ListOfCustomers>
</xsl:template>
<xsl:template match="CustomerSet">
	<xsl:apply-templates select="AddressSet/Address[1]" />
</xsl:template>
<xsl:template match="Address">
	<MyCustomer>
		<Id><xsl:value-of
select="/Customer/CustomerAccount/ResponseHeader/CorrelationId /></Id>
		<AccoutName><xsl:value-of select="../../CustomerName" /></AccountName>
		<BillMonth><xsl:value-of select="../As/Above" /></BillMonth>
		<Product><!-- as above --></Product>
		<Address><xsl:value-of select="Address" /></Address>
		<Zip><xsl:value-of select="../ZipSet/Zip[position() =
current()/position()]" /></Zip>
		<!-- I'm honestly not sure if the above wrangling is legal. -->
	</MyCustomer>
</xsl:template>
