Okay, getting the pedals off on a new bike should be doable. Sometimes getting pedals off on an old bike that has had the same pedals on for years or pedals that were tightened down by a gorilla of a guy can be beyond my strength to loosen. That's when I take the bike to the bike shop.
Can get confusing as to which direction needed to get the pedals loose or to tighten. Simple way to know. Put the wrench on the pedal and turn the crank. Turning the crank, backwards will loosen the pedal. Turning the crank forward, as when pedaling, tightens the pedal.
Most pedals, today, use a #8 allen wrench on the inside of the pedal shaft, but some still use a 15mm metric open end wrench. Some are setup to use, either. Note that you won't get any bike tool that has a #8 allen wrench. Way too big, so you'll need to buy one. Same for the 15mm open end wrench.
When removing the old pedals, be sure to retrieve the washer that fits on the pedal shaft and that goes between the pedal and the crank arm. Sometimes its stuck on the pedal shaft and sometimes it's stuck on the crank arm. The washer prevents wear on the crank arm. Don't install a pedal without that washer. Also, be patient when threading on a new pedal. It's a fairly fine thread and can sometimes be a little finicky to get started. Whatever you do, don't force things and get it cross-threaded. Then you've ruined an expensive crank arm.
Absolutely, do grease the pedal shaft threads when installing a new pedal. You'll be glad you did if you ever want to remove the pedal, again. I just borrow some all-weather multi grease from my husband's shop. Don't think it has to be anything bike specific. Just a grease that won't dry out or dissolve with exposure to the elements.
Sounds complicated, but it really isn't. The biggest issue for me and the thing I can never predict is how hard it will be to loosen the old pedals.
