How do I put the ILE in RPG?

I've read the IBM stuff, but it's still confusing...

I've been using RPG/IV without its ILE components (binding, procedures,
modules, etc.) because of RPG/III compatibility requirements (vendor
software).

I'm at the point now where I have a lot of shared code between my programs.
>From what I read, I can create procedures with prototypes, and bundle all
these together in a service program, and reference the service program from
RPG.

So, could someone please verify the way I think this works.

1. I write subprocedures and compile with PDM option 15 (CRTRPGMOD). I then
have lots of module objects on the system. Do I keep these after creating a
service program?
2. (I don't know the specifics) create a service program from all the modules
(CRTSRVPGM?)
3. Insert /COPY members into my code for the procedure calling interface (P
specs)

Is there an advantage of having one large service program versus service
programs segmented by function? What steps are necessary when a service
program module needs updating?

How does this change how I create my RPG/IV programs? For compatibility, I
have compiled using option 14 (CRTBNDRPG). Do I have to abandon this setup and
create program modules instead? How do I interact with the service program? Do
I need to worry about activation groups when I use the service program? 

I know I should get a book. Which RPG/IV books have decent information
regarding procedures and prototyping, and the other "fun" ILE stuff?

Thanks,
Loyd
