To force a particular program to launch with user defined properties like in Counter Strike, you can set the desired parameters in Set launch options.
Open Steam, right-click Counter Strike, then go to Properties. Search for Set launch options and type -freq (desired refresh rate) like -freq 75.
I am not sure if you can set resolution along with refresh rate. If so, add it to the launch options; otherwise just set manually the resolution as desired from the video options, which is also permanent as said earlier.

No, unfortunately you can neither repair nor modify your vehicle. There is basically no need to repair vehicles, because you can simply "respawn" any vehicle you could have destroyed with the "Car on Demand" app. I have completed about half of the game and have not come across anything to modify a vehicle, but feel free to correct me if something comes up later.
As Lyrical already mentioned in a comment, you unlock new cars for the app by simply entering them. If it is the first time sitting in the type of vehicle, the message "new vehicle unlocked" will appear in the top right corner and then you can buy access to it in the app. Another way to get cars (often rarer ones) is to hack civilians' phones. To make this easier, you can unlock a skill in the "Hacking" branch of the skill tree that marks civilians with especially valuable hacking opportunities (including cars, songs, crimes and rich bank accounts) with a blue square, so you can already see them from afar. The chance of finding vehicles that way is still rare though. Hacking people's phones is one of the few things you can do while waiting for a multiplayer session to start, so that is a good time to go searching for people with cars.
A good way to unlock sports cars, is to play Fixer Contracts that require to race through the city with a given car (which was already a sports car in the first mission I played). You can unlock new fixer contracts by hacking ctOS towers, which reveals new missions and points of interest in the area.
If you want a specific car from these missions, here is a list by segmentnext.com with fixer contracts and the vehicles you will be driving there.
