Hello cluelesscollector, welcome!
It sounds like you wish to be respectful and appreciative of those who have passed and the love and time and effort they have put into their collections. This is nice to hear.
The more you get to know, the better off you will be to decide what and how to do whatever you decide to do with the stamps.
First get an idea about how people collect and think about stamps and covers (envelopes). Get a Scott Stamp Catalogue from a local library (or an old one off
ebay) and read the front pages. Take your time, look up terms you don't understand, read again, look at some stamps, read the pages again.
The front pages tell you how stamps are valued and determined to be certain varieties or not. Some of the info might be beyond what you know now but do not despair. Just get a general idea of what it is all about.
Scott is usually a generalized type of catalogue 9except for the specialized USA book) and will not have detailed information about many countries. For this extra info, which might tell you about a Great Britain oddity or a Chinese rarity or a Canadian error, etc, etc, you need the specialized catalogues and perhaps booklets of that country's stamps.
Are there stamp tongs available to handle the stamps with? Otherwise you will get finger oils and stuff on the stamps. A good light, a magnifier (or a few), a loupe with extra magnification, perhaps a perforation gauge and a watermark tray and fluid (If you want to go really deep), a ultraviolet lamp (different types depending on which country's stamps), more catalogues, etc, etc.
But again, don't worry. I have lots of this stuff myslef and only use it once in a while, all depending on what I am studying at the moment or what I am doing. I use the catalogue at the library. It is nice to have one yourself, but not necessary.
Look at
ebay stamps categories and see what people are selling and see if you can see what is good or bad or fake or forgery 9yep, it's here in stamps too, wherever money is). This forum is great to ask before you buy anything of value to get opinions or other options you might not have been aware of. Read a bit on Stamp Community too. Lots of knowledge is already written about on here.
Don't feel you need to know it all now. It takes time like anything to appreciate at it's fullest depth, if you wish to. Some just buy what looks nice and don't study or delve deeper. Some delve deeper and don't buy (that's me). Whatever is fun and is you and is what you wish to do and the dream you want to follow.
Just pick a country and start there and see what you have.
Remember to show us some pics and ask questions too, even if they are common or damaged, it's always nice to see stamps.
There is also a web site called Ask Phil (philately) that has a glossary of quite a few but not all stamp terms.
