Siblings share parents.
1st cousins share grandparents
2nd cousins share gr grandparents
3rd cousins share gr gr grandparents.
The MORE ancestors you share, the more odds of having the same genetics, etc. You can go to 5th cousin, or as far back as you can define the common ancestor. You are still "related".
I am sorry I didn't reply to your email, have been swamped. In terms of finding common traits, so forth, you have more probability of finding info perhaps in the last 100 yrs, maybe more. Earlier information will exist.. it will not necessarily be as explicit as you may want.
For practical purposes.. if you have located your gr gr grandparents, you might choose to do a family tree that 'comes down' from that one couple. It can be more difficult, since genealogical records of more recent/ living persons tends to be more confidential.
The common genealogical records (dates of birth/marriage/death, etc) may be somewhat broad. Meeting and communicating with these distant cousins (ie a reunion?) often gets people to sharing family records or other "under the radar" information.
edit-
yes, you have a pinch of the same genes.. but they are less concentrated. IE.. if grandparents have brown eyes, you are much more likely to inheirit that gene, and the same applies to other grandchildren. By the time you go back many generations.. you dramatically increase the number of ancestors that you do NOT share.
There are numerous other things that do come into play.

Blood is blood. While I am not knowledgable enough to give specific details, I can say that, yes, that is still relation. Now, while I think most people are usually not familiar with 3rd cousins, let alone 4th cousins, they should still be invited to the family reunion.

Relationship is relationship no matter how far back it goes. However, I don't think there are any laws against 3rd cousins marrying. Actually if you trace your family back far enough, you will find distant cousins did marry. There are some people who have married a distant cousin and didn't know about it until they traced their ancestry.

You have a pinch of the same genes of your TWELFTH cousins.

You can marry your second, third, etc cousin with no problems, unless you have hemophilia or some other genetic disorder. If you are in the USA, and your ancestors were here before 1850, it is almost a certainty that somewhere along the line one of your ancestors married a first cousin, which is legal today in most countries and 26 states.
