1. trading col usually is good to be avoided; it's incredible how much it slows them down the lack of courthouses. And usually after it's founded, they don't research it till way later.
2. if trading col is to be avoided, philo is a nono trade!
And definitelly not for monarchy/calendar... Philo opens lib/nat; philo is researched... post islam and all the crap usually if the religion was founded(ok, darius will go for lib., but beside him - plus you might want to trade him aesthetics fast, so he builds spaya, so he goes fr, so he doesn't bother with lib.). At worst, you trade it for feud/cs/machinery(with mc turn before). All that while putting 1 turn in each so the trade is ok and you get some cash.
Honestly... was like: col for alpha, sally; col monarchy, justinian; alpha maths darius; and stop. Aesthetics(you have marble and 2 capitols... really, parth and glib should be there). At aesthetics, part research calendar, part construction, milk aesthetics(calendar, construction, iw, stop); but keep philo...
You really didn't need calendar when you must go hr anyway...
3. you'll hit wfybta in no time with this trading; why get masonry? **** masonry... you have here 5 and 10 techs people(wfybta wise...).

ragnar - 5; sally - 10; darius - 10 I think; justinian - 10; 1 was masonry...
and ragnar is the only one you can easily get to friendly with religion/hr; it's not like you'll run theo too soon, at least because probably it'll be a long while till you'll have the prereqs. Without theo, justinian/sally will get to friendly, but even 2 mis steps and you're out(you'll have +8 from religion, +1 from years of peace, hopefully +2 from each "our open borders" and "years you supplied"). With justinian you're just about to eat -2 from refusing to stop trading and refusing to join war when ragnar will declare on him.
Plus you just don't want theo as there'll be eons till you'll war again...
4. hr the second you got it... it's +5 diplo with ragnar at same maintenance... even if you'd have infinite happiness... it's not like barbarism gives you any bonuses... Leaving aside you'll be the odd man out who doesn't have this bonus with ragnar...
5. you're perfectly safe... sally is a nice chum and ragnar will attack justinian anyway...
6. expand; now! You'll always find something better to do, and then you'll wonder why those new cities have 0 infrastructure... well, it's because you just built them
Go east, block sally(he probably won't settle behind you, just make sure you wait on the barbarian city and raze it after sally softens it up(or whoever, all ais love to get the city half the map from their capitol). Grab the spice/gold(you have calendar now
) and park a settler so you plant the pig/fish far east when it's the barbs are gone.
