Not to sound flippant but I think you will find the answers (and quite
in-depth) to many if not all of your questions by searching the
archives of this newsgroup. The questions you have been posing are all
very common and have been covered a number of times here and there is
a wealth of beginner knowledge and product info and recommendations.
If you are using Google Groups to access this newsgroup there is a
search bar in the upper right and a button says "Search this group" I
guarantee if you search for "infuser" or "infuser suggestions" you
will find a lot of info.
