Ok, thanks!! In the videos I've watched the guys have kinda had to gently wiggle things around to get it apart. I figure it's gonna be a bit of that -- but I'm pretty sure I can do it. Seems pretty straightforward after you get it apart.
And I'll definitely remember to turn the water off first. Lol
Turn the water off, then drain the system at a point lower than the faucet on which you'll be working. A bathtub is usually a good choice.
Do not ask how I know this.
Or there may be cutoff valves under the sink... 
Of course. Duh. The last time I dealt with a bad valve, it was in a bathtub, which didn't have cutoffs.Or there may be cutoff valves under the sink...
I'll just shut up now.
Mine do now. One bathroom anyway. Cold winter several years back froze the copper pipes right where they came out of the slab. Had to use a pneumatic hammer gun to break out the concrete so a union could be soldered in to allow repair on the rest of the tubing.
Since there was already a hole in the sheet rock, built a nice oak frame to go around it with some oak plywood secured by screws in the center for future access. It’s behind a chest of drawers so it’s not noticeable.
The "buttons and springs" that Xseler refers to are commonly known as Delta cups and springs. $3.00 or so will buy you a set (2 cups, 2 springs) at a well-stocked hardware store, or at the faucet shop that Dave mentioned (or maybe even at Loew's or Home Depot). I would buy a set over the weekend to have ready on Monday morning. There are two essential rules to plumbing: start early in the day, and early in the week. Good luck! BTW, Delta cartridges aren't too expensive even if you mess one up, usually about $40.00. If it gets to that, be sure and take your old cartridge with you to the faucet shop so they can match it up.
Most of the time when I do something like that I just shut off the water and take it apart. Then take the parts to the store and let them figure out what it is and find what they think is correct. Then take both and look at them side by side. Worst case NO ONE has it and you take yours home and put it back together and buy a whole replacement faucet and go from there.
Worked in a building in Lawton as maintenance for all the apartments and used to have to change the two handle faucet rubbers out. The bad thing was that if you didn't know they were leaking the water would etch a channel in the seat and they were not a replaceable kind. I had a couple where I ended up machining the seat a little so it would seal and shut off. Did some major plumbing projects with the owner and his son in law at one point and one of them forgot to cap a line. Water got turned back on in the basement and it started spewing in one of the vertical chases where all the lines were ran. The DERP son in law stood there and just looked at it like a deer in the headlights. I pushed him out of the way and stuck my thumb in the line and plugged it off, told him to tell the owner to shut the water back off. Otherwise it would have been just like the 15 minutes of water video posted except we were on the 6th or 7th floor. 30 seconds of water was enough to have some start coming into three or four apartments below that point already.

If you decide to do it yourself and it's a Delta bathroom faucet, when you try to take the retaining ring off and it won't turn very
easy, don't force it or you could twist the assembly that's nailed or screwed to the wood in back. Then you will really have a problem.
My plumber said that happens a lot and then you are looking at lots of money to fix. Also get all the parts you can as the spring
and washer set might not stop the leak. Get the adjusting ring too or better yet get on Amazon or other site and get the complete
faucet repair kit which has all the parts. It sells for $25 bucks or so. Good luck.

Yep, just cut off the two valves under the sink, get busy with the tub set and you’re golden.
