I see alot of people who file the I-130 and the I-129 either at the same time or file the I-129 after the I-130 check is cashed. Is this for people who are doing a Cr-1/IR-1 and a K-3 just to see which gets processed faster?

I am hoping that I didn't mess anything up...

LOTs of people are wishing they didn't do the I-129F at all and just did the I-130.
Me for one!
K3 is a dinosaur at this time.
USCIS loves people doing K3s as they make a LOT more money for a LOT more hassle for the petitoner.

if uscis had loved those who file k3 cos they make alot of money they should be approve faster now, so that will generate more customer for them, on k3?

Don't worry, you didn't mess anything up, unless you do want to file both and see which gets processed faster. I did, however by the time my K3 was at the Vancouver Consulate, the fees were pretty much tripled for AOS, and the thought of not being able to work for about 6 months convinced me to stick with CR1.
If you do decide to go ahead and file for a K3 as well, you can send off the I-129F as soon as your have your NOA1 from the I-130. (You have to put the receipt number from the I-130 on the I-129F.)

Ya, its the not working for many months that makes that route kind of silly imo. Might was well let the hubby toil away in Toronto and bank up our house down payment while we wait. Beats the alternative of him sitting here and being a househusband...

I just had another 'ono!' moment and thought perhaps I should be working on something else, immigration wise.
