When spelled Leanan Sídhe, it is pronounced "Lah-nan Shee-uh." This is the older form, pre-Caighdeán spelling and pronunciation. The leanan sídhe was a member of the aes sídhe who would grant inspiration, though the inspiration came at a cost of an early death, frequently after insanity.
It is not uncommon to find claims that sídhe is pronounced "shee," but that is how you pronounce the Caighdeán spelling of sí. When the IPA (ˈʃiːə) is examined, it is clear that there is a distinct "uh" sound at the end of sídhe. Contrast that with the IPA for sí, (ˈʃiː), and it is obvious even from a cursory glance that there is a difference in pronunciation.

It depends who you ask. If you are an ancient celt or a modern practicing the old religion, then you would probably think highly of the Sidhe. Some people who have difficulty with religious traditions not their own might take exception to the Sidhe. I am only guessing but perhaps certain Christians might think the Sidhe were wicked as they are part of the pre-Christian belief structure, or the faerie realm. Many Christians have respect for other mythologies and even feel they can provide a valuable perspective, and that multiple narratives contribute to a fuller understanding of basic reality and mankind's place in the world. It is my understanding that the Sidhe were akin to a race of high elves. I am unaware of any faerie tradition that the Sidhe were wicked, but perhaps they were somewhat like wolves in sheeps clothing. I am familiar with the Tuatha de danae, who were also highly regarded by the pre-Christian inhabitants of Ireland.
Sidhe, rade, and march could all be used to describe a group of fairies.
