Good to hear you're taking it easy now
But as far as starters go.... if you're using liquid yeast you should always make a starter (unless you're intentionally underpitching to get a lot of esters/phenols.)
Mr. Malty yeast calculator shows a 5 gallon batch needing 153 billion yeast cells... the wyeast smack packs only have 100 billion and that's under perfect conditions (i.e. production date of today, plus strict temp control.) Most likely you're not starting with that much.
However, you'll be fine... don't let me scare you. You'll still make beer and it will most likely be delicious if all of your other processes are locked down. But there are very simple steps you can take to make truly great
beer and one of those happens to be making properly sized starters.
