Do we need to make an appointment to buy Mac Pro ?

You do not need to make an appointment to purchase products from an Apple Store. When you are taking something in for evaluation or repair, that's when you need to make an appointment.

Good question. It may be worth dropping into the store and asking obliquely if someone would be available to take you through the initial stages of setting up should you decide to buy a Macbook Pro.

In the US, Apple-owned stores stock the standard configurations. You can walk in and buy it like a toaster. Many stores will no longer take cash for major purchases of iPhones or Macs.

If you need something special added, that will take some time to get the parts and put them together, and smaller store may not carry high-end configurations at all. Most MacBook pro memory and some drives are soldered to the mainboard, so "adding memory" now means literally ordering a different model -- they cannot add that stuff in the store.

Other ways to get your Mac configured specially is to order online for delivery in store, to order online for delivery to your door (provided someone can sign for the delivery during the day, or if they just leave it, packages do not get stolen off your doorstep).

Or you can order online from a reseller for delivery to your home, possibly at a slightly different price. be sure to ask about the warranty being the same. I do not recommend third-party warranties such as those offered by Best Buy.

Be sure the current model fits your needs. It is a design with serious limitations and may not offer much benefit for your purposes.
