Where should I put my utilities? How can I use my individual form? (Delphi)

Question

I have been using Delphi for a little over a month, but I still don't know how to do it right.

If I have methods that I can use in many projects, should I put them in a Unit, form or DataModule? I did not use the block (by itself), New-> Unit. Should I put my utilities there? If so, is there an example that I can look at, a textbook or something else. I have used DataModules in the past, although it gives me the impression that it should only be used when I am dealing with databases, etc.

Another thing, I customize some forms (for example, a form with some TEdits that do certain things). To use this, first add this to use in .dpr
CustomizedForm in '\CForm\CustomizedForm.pas' ;
then I add CustomizedFormto use in my main form (where I will use it).
Is this the right way to do this? I just guessed it seems to work, although I'm not really sure if this is the right way.

I myself create a group of projects that includes the package MyProjectUtils.bpl, and I put all my utility modules and classes in this package. I never deploy it as a package, but since they are wrapped together, I can always verify that they all compile correctly, and that they are all immediately available for viewing in the IDE, etc.
