Congrats on the license, If you are only wanting to access one repeater, a basic simplex node is all that is needed, remote base gets a bit more complicated, and is primarily used for controlling a radio, i.e. changing frequencies/channels etc, and has limited compatibility. If you just setup a simplex node, much simpler and will work fine for talking over one repeater/frequency.
When you setup the node, want to make sure there are not courtesy tones, or hang time setup, as that will cause an annoyance for users of the repeater... basically in the node configuration file rpt.conf setting duplex=0 works well... I do the same thing to link to local repeater system here...
I would use whatever radio you want to use, I have an icom 207h older rig, but works great, I have used an icom706mkiig, and Kenwood TM-V71A's as well, it's just personal preference, ease of interfacing etc...
Motorola radio's are fine, if you have someone who can program them for you... I have used ebay and
qrz.com to purchase older radios, sometimes find quite the deal.
