Oh my, oh my! Is this your first? Owen is my first and I can tell you the first 3 months are SO HARD! First I will tell you it does get better, and you aren't alone feeling overwhelmed and second guessing - I think more of us have been where you are then haven't! Sometimes when things get all mushed up it helps to step back, and just watch for a few days. Stick with the EASY idea of eat, play, sleep - but watch him and write down when he seems sleepy, hungry, what he does for each - that sorta thing. Then its all on paper with the times, and you can mull it over when you have a moment. Just a thought!
I'll try to help a little. Yes, she is WAY too young for PUPD. I think her biggest trouble is - she is overtired and overstimulated because of that. Usually at this age, when you SEE a sleepy sign they are already crossing into the overtired place. The babies who hate the swaddle most often need it the most. At this age they have little control over their arms and when they flail around its startling. Have you seen the Miracle blanket - some moms have great results with it.
I think at this age, the most he can probably handle is a feed, cuddles and loves, a diaper change and then start the wind down. I know it will seem like he is sleeping all day lol - but he needs a ton of sleep to grow! I would move him to his crib in his room now - but that is my opinion only. I think it's easier for babies to sleep when they have their own space. This is certainly up to you.
Are you doing the 4S's for the wind down? Here is a link:
https://babywhispererforums.com/index.php?topic=64277.0 Perhaps try some white noise? A special white noise CD or a fan on high facing the wall is what I use. Is he using a paci? May help some too.
Are you trying for the 3 hour easy? I made a little routine as a guide - I made the times a bit different then the book because I think he needs a bit more sleep... this is just my suggestion and someone else may give you different advice.
E: 7.00 wake up and feed
A: after feed til 8am then go to the nursery and start the wind down
S: 815am asleep for 1h45m
E: 10.00
A: after feed til 11am then wind down
S: 1115am asleep for 1h45m
E: 1.00
A: after feed til 2pm then wind down
S: 215pm asleep for 1h45m
E: 4.00 feed
A: after feed til 5pm then wind down
S: 515pm - catnap for 30 - 45 mins
E: 7.00 (cluster feed at 7 and 9 if going through a growth spurt)
A: after feed do bath (if it isn't too stimulating) bedtime routine
S: 7.30 bedtime
E: 10 or 11pm dreamfeed
Again this is just a suggestion until he starts sleeping better - sleep begets sleep. You should always wake for a feed - at this age they really need those calories. Remember EASY is just an idea - eat, play, sleep - that's all ... we do it in this order to prevent AP like feeding to sleep. The times... well try not to stress - so long as there is something even a little something between the E and the S all is good.
For pat/shh - you can find something that works for him. Be it patting, rubbing back, butt, head, jiggling, just a hand on the back/belly, humming, soft singing, gentle words, nothing. I feel maybe if he isn't overtired maybe the regular pat/shh will work? Here is a helpful link:

Do you know if he is spirited? Here is the quiz:
https://babywhispererforums.com/index.php?topic=52283.0 - it helps to know, there are good links in the FAQ about each type of baby.
I hope this helps some. I usually don't respond to EASY questions but your post tugged at my heart, and I hope something here helps you. Please don't think you are alone. I think the most important things to remember are - there is always a tomorrow, this too shall pass, Start as you plan to continue, and relax-breathe-and enjoy your LO cause man, this time is SO short!
Big hugs to you!
