All right, here’s a start–once you’ve tried this you can see how close it is to what you’re looking for and we can tweak from there.
Open File > Compile and click the “All Options” button at the top if it’s not already selected. This will expand the window so you’ll see the sidebar of options (Contents, Separators, etc.). Your screenshot shows this already selected, but I’m including this step for the sake of being thorough.
Click the “Format As” pop-up menu at the top and scroll down to the bottom to select “Manage Compile Format Presets”.
This will bring up a window listing all the built-in compile presets available and will also show you any custom ones you’ve created or imported. It’s alphabetical, so scroll down to find “Times 12pt with Bold Folder Titles” and tick the check box.
Click “OK” to close that window. Now you can click on the “Format As” pop-up again and you should see “Times 12pt with Bold Folder Titles” among the options listed under “Predefined Formats” in the top section. Select that.
This will give you Times New Roman font, double spaced lines, indented first lines. It will leave in place any italics you used when writing. It will also include the folder titles, as you see them in the binder. Going by your previous time through this, I think you may not want these: if you have the chapter title written directly in the document along with the chapter text itself, you won’t want to duplicate that by also including the folder title. To remove the folder title, select “Formatting” from the left sidebar and then deselect the “Title” column checkbox in the Folder row.
Now, assuming that you did put your chapter title directly in the document, I will further assume that you also centered it and would like to keep it centered. To do that, click the “Options” button in that same Formatting pane of Compile and then check the box midway down to “Preserve Alignment”. You may want to also then check “Centered text only” to make sure everything else gets cleaned up, or you might prefer to leave that unchecked if you intentionally have right-aligned text within your manuscript.
Finally, since your Title Page is most likely set to compile as-is and you mention that you’ve used a different font when drafting, select the “Quick Font Override” from the list on the left. Choose “Times New Roman” from the pop-up menu and check the box to enable the override. This will ensure that the Title Page uses TNR for the font as well, since it is otherwise compiling “as-is” and not having its formatting overridden by the settings applied in the Formatting pane.
That should take care of most of what you’re after, but give it a try and see how you like the results. If you you don’t like the way the chapter titles are coming out, you may want to try selecting them in the editor and then applying Format > Formatting > Preserve Formatting, as Ioa mentioned up-thread: this will preserve your editor formatting, as the name implies, so the settings from the compile formatting pane (line spacing, font size, etc.) won’t affect it. It does mean though that if you’re using Century Schoolbook there, they will compile as Century Schoolbook even though the rest of the manuscript will be in Times New Roman–the Quick Font Override won’t affect that. You can however go back to the “Options” in the Formatting pane of compile and check the box in the bottom section for “Preserve Style only preserves” and then tick all the boxes below that which you want to apply: in this case, probably all of them, which will allow most of your formatting for the titles to remain while still using the compile settings for the actual font.
Alternatively of course you could switch your Quick Font Override to Century Schoolbook and compile everything in that instead of Times.
Anyway, give it a try and then report back on where you’re at and where you’d like to be. Details on what you’re getting compared to what you’re trying to achieve will help figure out where we need to alter the set up.
