Hi all, I am brand new to the world of umbraco and until playing with it had never seen a word of xslt so this may seem to many like basic thing to ask.
But as I've been dropped in the deep end to rebuild the company website at my new job I'm left with little choice.

Either I'm searching the wrong thing, or umbraco tutorials are few and far between so where better to ask then here with you guys :)

Basically what I want is a 2 layer navigation system, the first layer is always the same and would go:

Home - Products - Services - Contact

The second (sub navigation) would be based on the above depending on where you are, so for products:

Product 1 - Product 2 - etc

The same sort of thing you see all the time, nothing special. 

My strucure is something like this:

-Home
-Products
--Product 1
---Product 1 details
--Product 2
-Services

From what I've read already this is wrong anyway as everyone says that everything should be inside 'Home' which I can live with, and I've found guides which say how to make the macro display the 'Home' link as well even on a different level. BUT. My first problem is that under Home, I want sub navigation, so the structure would become:

-Home
--About us
--What we do
-Products
--Product 1
---Product 1 details
--Product 2
-Services

So my first problem is, how would I structure this is the umbraco prefered way, but still make it make sense like above, at which point navigation should be fairly simple for the top level.

Secondly, both top and second level nav have a current state, but I want this to echo down the tree, so for example when on the page 'product 1 details' both 'product' for the top level, and 'product 1' on the second would be in their 'current' state so how can I make this work too?

If anyone has any useful videos, links, websites, tutorials, free ebooks, tips, advise, or wise old wizards looking to help a young developer, I'd be unbelievably grateful.
As I say I'm new to everything involved here (I'm not even an advanced user of IIS or ASP.NET themselves, I'm an Apache and PHP kid, but you go where the work is right? Haha) so I am completely at a loss on how to proceed and make this lot work.

Thanks for any help anyone can give, and sorry if I've drivled on a lot there, 
Martin :)
