If you are going to get started in reloading I suggest you make one purchase right now. The book is titled, Modern Reloading Second Edition by Richard Lee. It has a great explanation of the process as well as a review of the more common and available tools used in reloading. It also have a lot of load data or "recipes" if you will for loads of tons of calibers. I suggest you get at least 2, preferably 3 loading manuals so you can cross check load data on cartridges.
To get started buying one of the "kits" by Lee, Lyman or RCBS is the way to go. The kit will have the majority of the tools you will want. I have a personal preference for RCBS in the press (rock chucker is best single stage IMO)and powder throw myself. You will also need a set of scales for powder measurement to calibrate the powder measure. Dies by any of the manufacturers are good. Just make sure you get the kind that will fit in your press. I like the universal thread style as you can buy from any manufacturer then. You can use the press to seat dies but I prefer the Lee hand primer for that job myself. Much better feel for when the primer seats and you don't crush them with the press leverage.
Pistol dies come in a 3 pack, rifles normally in a 2 pack. You want a carbide pistol die set. Saves you tons of time since you do not need to lube cases.
Use the loading manual to find a powder that will do as many of the cartridges you want t load. Some powders are very specific like small cases or very large cases or fast / slow burning rates. There are several pistol powders that will handle multiple handgun cartridges form target up top magnum loads.
The 3 cartridges you list can be covered in probably 2 powders. One for the pistol and one for rifle.
The variables are one of the big fascinations with reloading. Various powders can provide peak accuracy and or velocity. They rarely are the same load for each goal. The max speed is seldom the most accurate load. You can get bogged down in the different powders and slug selection to keep you busy for a lifetime in just one caliber like .308 and 30-06 for example.
Do some reading then you'll have an idea about getting started. You can go ultra cheap with the old Lee hammer style dies that do not use a press. I do not recommend you do this. Using a hammer to load a cartridge is hardly a precision way to go and it is very very very slow. I also do not like using powder dippers, too imprecise especially in some pistol powder recipes where using only 4 grains of powder is the norm. That is a tiny amount of powder and I know of a few 38 special loads that use only about 2.5 grains of powder. Keep in mind that there are 7,000 grains in a pound of powder.
