Questions you have asked:
Do I need an SWR meter? Yes, you should have one and tune the antenna. You are installing a 40 to 50 watt transmitter costing $400-600 each. A $50 swr meter is not too much to spend to protect yourself against end-user claims.
Do I need to solder the center connector? You need to solder the center conductors together before inserting them in the tip.
30 miles through mountainous terrain? Not at 154mhz. Anything over 50 MHz is considered LOS [line of sight]. To do the job you are trying to do will require a "repeater" located at a high spot centrally located that can see the vehicles requiring its service.
There is a wealth of knowledge that is required to properly install a mobile communications system. The easiest way to obtain a lot of this information would be to become an amateur radio operator. It is a learn-as-you-go method and it is inexpensive (the test costs $14). There are three exams, but you only need the first to get on the air. You can study for each of the three exams for free at I would be glad to give you the exam, if you are in the SE Georgia/NE Florida vicinity.
