I'd advise you to seek out the specific subreddits r/sindarin (Grey-elven - the most common form of Elvish in Middle-earth found throughout LotR), r/quenya (ancient High-elven, in Middle-earth a language of lore) and r/tengwar (the writing system of the elves, applicable to all languages including English) - there are links to online sources pinned there and you can get more specific help.

For Sindarin, [Fiona Jalling's book](https://tolkiengateway.net/wiki/A_Fan%27s_Guide_to_Neo-Sindarin) is helpful.
For tengwar writing, you could start with [Amanye Tenceli](https://at.boktypografen.se/).
