I like to do a total recap -- replace ALL capacitors above .001uf with new and then power up. I replace capacitors one at a time, one lead at a time. Take a lot of high resolution photos to refer to if in doubt.
As for soldering technique, I too like the pig tail connections for hard to get to areas or fragile areas. By "pig tail", we mean to cut the old capacitor wire leaving about 1/2 to 1 inch length stub. Then take the new capacitor and wind a few turns - say 4 turns - around something like a push pin. This creates a tight coil. Then take the coil end of the new capacitor and push it onto the stub. Solder the stub and you got a good nice looking connection.
Another good technique when you want to solder directly onto a terminal is to heat the terminal and use an ordinary wood tooth pick to create a tunnel in the solder. Leave the tooth pick in until the solder solidifies. Then remove the toothpick and insert the capacitor wire.
Sometimes the terminal is crowded with lots of wires and those old terminals will break if you use a lot of force to remove old wires. Many times its best not to remove the old wire but to cut it off and use the toothpick technique. The best judge is you evaluating what needs to be done.
I have more success using toothpicks, then the pigtail. For some reason, I tend to avoid J-hooking wire connections as I view them "hookie".
When you order your capacitors, also get some Spaghetti insulation to insulate the capacitor wires. Its not very expensive and easy to put on and provides protection just in case one lead touches another.
Also, for about $7 you can purchase a Solder Sucker - great for removing blobs of solder from a terminal strip. I heat the terminal until the solder melts, and then put my solder sucker over the terminal to vacuum the solder off. Mine is spring loaded and you have to cock it first and press its trigger to suck up the solder.
Soldering iron vs Soldering Gun ... for TV work I like to use both.
Good luck and take time your time and enjoy the recap experience. Don't rush it.
Oh but the way, ALWAYS discharge that picture tube after you remove power - ALWAYS. If you don't know for sure now, please ask. Its an important safety issue you must follow.
