I've got most of it (creating a excel sheet from Delphi) working but can't find the correct
 wording for freezing panes.

I'd also like to be able to use validation on cells.

Is there a good resource that I can find this info for myself?

At first you can import Excel library (Project -> Import Type Library -> Microsoft Excel Object Library)
Then you can look at the imported code and find things like consts, param counts etc

At the second you can use MSDN to find description of all Excel interfaces and objects. For example here is description of FormatConditions.Add method:

  XLApp.Range['A2:A2'].Select;

Validation:


procedure TForm1.Button1Click(Sender: TObject);
const
  xlValidateWholeNumber = $00000001;
  xlValidAlertInformation = $00000003;
  xlBetween = $00000001;
var
  XLApp: Variant;
  Validation: Variant;
begin
  XLApp:=CreateOLEObject('Excel.Application');
  XLApp.Visible:= True;
  Validation:= XLApp.Range['A1'].Validation;
  Validation.Add( xlValidateWholeNumber, xlValidAlertInformation, xlBetween, 5, 10 );
  Validation.InputTitle := 'Integers';
  Validation.ErrorTitle := 'Integers';
  Validation.InputMessage := 'Enter an integer from five to ten';
  Validation.ErrorMessage := 'You must enter a number from five to ten';
end;

In the validation piece I needed to add
Validation.ShowError := True;
