Main Water Shut-Off Valve

I have to replace the hot water supply valve for my washer, so I want to turn the water off for the entire condo. In my utility room, there are a few pipes with valves on them, so I want to make sure I hit the right one (I'll of course test it, but would like to get it right on the first try).

I'm thinking it's the one with the yellow handle. The pipe on the left top says hot on the tank, the pipe on the right top with the blue knob says cold on the tank. That pipe goes into the wall, but before it does, there's a t-junction which leads down to the yellow handled valve which then also goes into the wall. There was also a pipe on the left bottom of the tank which I think had a small valve on it, but don't remember now. :p

Any ideas?

Oooh, you've added another wrinkle for me, I didn't even think of soldering. That'll be fun.

I went to Lowe's to look at the type of valve's they have and I was (foolishly) hoping that these things would be universal and named washer water supply valve. :p I saw valves labeled as boiler drain, garden, sillcock, etc. What is the specific name of the valve that I need? Is the size for them standard? I'd like to get new ones before taking the old ones out so the water isn't off all day. I included a picture of my current ones.

I was thinking of just replacing both of the valves - they're probably both 20+ years old and, if the valves are cheap enough, I'd rather just get two new ones in there now.

Ok, playing around with it a little more. I tightened up the packing nut a little bit and the leak lessened, but there was still a slight leak. So, I should remove the handle, then the packing nut, then the old washer. Replace the washer (what size and material?), hand tighten the packing nut, put handle back on. Then test and tighten the packing nut 1/8 of a turn at a time. Right? Do I still have to turn the main water off or is the supply to the washing machine enough?
