Skim parts 1 and 2. They have been covered and used before.

I will create a project of type "Cocoa Application":

'An application, based on the Cocoa framework, that is written in
Objective-C and relies on nib files to define its graphical interface.'

Design Tools should be read and understood. I am not familiar with
this yet.

Later features in this document can be left for later.

Might I use a single project with a few different targets. One for
the main program, and one for the parser (developed separately as a
plugin)

Xcode tracks certain settings at the project level. These settings
include your choice of version control system, the version of Mac OS
X to develop for, and the build configurations available in the
project. You can view and modify project-level settings in the
project inspector, shown in the following figure.

'The design tools are the part of Xcode that is responsible for
modeling the classes in your application and the entities that
represent your data. Modeling tools can give you a better conceptual
overview of your project than raw XML or a mass of source files. You
can customize the view to see the information you need most. Xcode
provides two types of design tools: class modeling and data modeling,
also referred to as entity-relationship modeling.

Xcode offers three tools—one to model classes and two to model data.'

I'm currently up to Part II: Design Tools, Class Modeling with Xcode
Design Tools.
