Yes, this is very valuable source. And Ramon is very helpful guy ;)

You shouldn't care too much about deployment in the beginning. You can
use your development image and just start it headless on any server to
do its service. Later on you will divide the image you develop on and
the image you deploy. You will add more tools which help you develop
and you will reduce the install base for your web app. For development
the answer could be the squeak-dev image. For the deployment the answer
is propably kernelimage which has everything stripped which you don't
need for a server app.
I'm myself in the progress of creating a deployment script. I have a
manually created base image (started from the official 3.9 image). And
I have a script which loads the latest code, closes windows, frees
some memory and creates a derivate image which is able to deploy.

You shouldn't just telnetting. It is still a oodb ;) Getting into OODBs
is quite easy as the reflect exactly what you model with your
programming. You just need to connect and request the top most entry in
the database (it is just a tree).
might be helpful for using GOODS with seaside.
gives the information about Magma you need. As long as you are not about
performance tuning the learning curve isn't very steep. Magma has its
one Mailing List you should subscribe to if you like to use it. Chris is
also a very helpful guy (as nearly everybody in the smalltalk community

The most important thing is the version number. 3.9 is the actual number
3.10 is in development. Which one to use you have to decide which tools
you want to use. I think most stuff is running on 3.8 image with moving
The flavours of images are for special purposes:
- squeak-dev : stuffed with goodies to ease development
- SMP : preinstalled modules to use the pier wiki with several
- squeak official image
- kernelimage: A Image with only the necessary stuff to run installed
- minimalmorphic: a kernelimage with a base version of the graphical
Take your time. You'll get into this automatically if you read this
list and maybe the newbies and squeak-dev list.

You are welcome :)
