Cfc's and flex

Question

I've been nose down in numerous Flex resources and due to the
abundance of "options" hope those more experienced can provide
clarity (thanks in advance for all responses btw).
1.) Flex can connect in various ways to various data
providers -- but presumably should be most efficient to a CF8
server(?) due to non-XML conversions (via RDS?/AMF?/ec4x???).
2.) Per the above is Flex able to call cfc's (presumably the
best format) ONLY via:
<mx:RemoteObject id="helloWorld" destination="Coldfusion"
source="NewCFComponent">
<mx:method name="GetHello"
result="GetHello_handler(event)" />
</mx:RemoteObject>
and moreover, is this resulting error indicative of a problem
in the Flex application properties or in the Remote Object:
[RPC Fault faultString="[MessagingError message='Destination
'Coldfusion' either does not exist or the destination has no
channels defined (and the application does not define any default
channels.)']" faultCode="InvokeFailed" faultDetail="Couldn't
establish a connection to 'Coldfusion'"]
3.) Following up on Q2, when defining a new flex project with
ColdFusion, can someone please explain the
"Use remote object access service" checkbox and LiveCycle
DataServices/ColdFusion Flash Remoting choices? Livedocs is worse
than useless, every demo app seems based on using localhost rather
than a network devServer so this and the next (configure cf server)
page might as well be hieroglyphics IMHO (ie. difference between CF
root folder, Web root and Root URL ???????)
4) I understand(?) that LiveCycle Data Services provides
extra features like Instant messaging, however requires a
(separate?) installation with "an application server" (though I've
also recall reading that LCDS is built in CF8)??? If my current
DevServer is IIS and Coldfusion, is this either/or to installing
"an application server" on the same machine? And is the LCDS
installation supplementary to the CF server or does it replace it?
Again, thanks in advance, I realize I may be waaay out in
left field on some of these -- but that is why I'm posting after
all :)

Oh also, I'm somewhat comfortable with DW CS3 (both HTML and
to create cfc's) and am just starting with Flex (Eclipse with FB3
and CF plugins installed) but would love suggestions on how to work
end to end so to speak.
Specifically, creating cfc's in DW, then presumably having to
import them into my Flex project seems less useful than say
incorporating the eclipse CF perspective but I cant seem to google
any results for such incorporating or even for using the cf-eclipse
perspective. Am I missing something ?
