Ohh yes newbie indeed and clear info on GMRS basics in programming is very scant and choppy on the web.

The antenna connection on this model is called SO-239 (female) and I have to look for antennas with PL 259 (male) connection? Most antennas I see online say they have N female connector; do I have to look for connection accessory that is called N female to PL259?

You can find commercial antennas tuned for 460-470 with so239 connectors (this is the end the antenna should have as your feedline will have PL259 connectors which mate to them)

If you do get an antenna with an N connector, simply look up a so239 to N connector. This will allow you to adapt an "N" socket to a PL259 plug.

You mean for repeaters in different cities?

Not really different cities.

I will usually append the fractional digits of the frequency in case there are more than one repeater in any city, such as:

HMD675
HMD525
GARY700
etc.

If the repeater has a "name" I'll use that instead:

NSEA
FOXRUN

Thank you guys, I learned a lot, starting from 0 to programming frequencies to now figuring out which antenna I’ll get and proper mounting.

Yeah you learn a lot, If you really want to learn more, like radio repair and how they work, become a ham operator :P Takes a bit of learning but what you learn follows everyday life, from radios to cell phones to wifi. You get an understanding for their strengths and weaknesses and failures.

For simplex operation, you should have the same frequency for RX and TX. This means you will transmit and receive on the same frequency. Remember, the last 8 channels in the GMRS allocation are repeater outputs. It is completely legal to talk simplex on these frequencies. For repeater operation, you will need to use two different frequencies. RX will be the 462.#### frequency, TX will be 467.####. The last four numbers of both frequencies should be the same.

I was looking at GMRS repeater directory and it lists output frequencies only like 462.550 or 462.725. Does it mean I just add an extra zero because the last 4 must be matching on Tx and Rx? So I would program repeater as Rx 462.5550 and Tx. 467.5500 ?
If repeater has access tone and they set it to say Tone D754N do I have to program the given repeater Tone to Rx and Tx frequency? So the rule is last 4 digits on Rx and Tx must match and also the PL/Tones must match on input/output?

That is correct for this band.  If it only shows 3 digits behind the decimal, and if that third digit is 0 or 5, you may assume that the last digit will be zero.  You can also assume that if the third digit is 2 or 7, then the last digit will be five. (ie 462.637 would be 462.6375)

PL tones quite often are the same on input and output, but that is NOT ALWAYS the case, and you may need different tones for RX and TX.  If you want to listen to all traffic, it is safe to put no tone on RX, and use a TX only tone to access most repeaters. - but then you will hear EVERYTHING on the frequency whether on the repeater or not, even bubble-pack radios.
