You don't need to buy multiple meters. That's silly. BUT, you'll need a real SWR meter. The built in ones are usually not great. Here's a link to a good unit that won't break the bank.

Just grab one of these meters and a 3ft or whatever length patch cable. You connect the meter to your antenna wire and then the patch cable between the CB and meter. They sell this exact same meter at every major truck stop but it's $5-10 more expensive. Detailed instructions also come with it and there's plenty of YouTube videos.
As for physically adjusting the antenna, you just shorten it/lengthen it at the tip. All the Wilson antennas have a little set screw at the base to make it even easier by pulling the metal whip out or pushing it in and then tightening the screw. Sometimes you need to clip some metal off of the tip of the antenna. It's fairly easy and can be done in a few minutes if everything goes right.

You can do it yourself if you have an swr meter.
You can do it with one of these: http://www.amazon.com/Astatic-302-01768-PDC7-Compact-Meter/dp/B000VXKINA/ref=sr_1_13?ie=UTF8&qid=1463005631&sr=8-13&keywords=swr+meter
Of course, takes longer than with an analyzer, but it works.
