I do not know the syntax highlighter, but I know the AST fairly well.
The first two points are fairly easy:

Color method temp variables and block parameter variables differently. Currently they are identified too generally as just #variables. They are therefore always the same color. Can someone point me to the parser classes that extract these features?
Color differently Classes and other globals? I'm trying to find this distinction as well in the parser classes. If someone familiar with the parsing and related GUI classes can give me some pointers, I'll do the work.
Let the user assign colors to the first 7 levels of parentheses and first 7 levels of brackets.

1) There is no differences in the AST about temporary / arguments declaration.
They are both at the level of the sequence node of the method/block (the body).
Thankfully we can ask for the parent and have a case for each.
You'd have to modify visitTemporaryDeclarationNode:.

2) There is no difference in the AST between classes / Globals.
Because Classes are in fact Globals.
You'd have to ask for the (self class environment classAt: aGlobal name)�� ifNotNil: [ class behavior ] ifNil: [ global behavior ].

A quick look seem that the behavior of the syntax highlighter is in the IconStyler class.
(again, don't know it, just checking this out quickly).
