I'd be happy to help. The best way to do what you are wanting is indeed to use templates. You can make a template and set it as default. However, songs are unique because when you pull a song up, it pulls up from the last version saved to your library-- it does NOT just manually apply a default template which would overwrite or ignore the actual data you've saved to it with the library. Now if you've never used the song before so it doesn't have any other template information, it may pull in the default template. But in most cases-- you'd just need to pick a template upon inserting a lyric (you can do it on the top left corner of the cue editor window so it's just one or two clicks. Then that lyric should be saved to your library, and next time you use it, it's already ready to go.
As far as the title page, I agree and personally do not use the title page in my ministry, although there are plenty of churches who do. To get rid of it you'd basically delete it from the play order on the left of the cue editor in the play order. (Right click it and click delete). Then save your template after that by going to the down arrow in the top left in the template selector, clicking save template, then do make default if you like from that same menu. Now when you load that template it should take the title page away too.
