Thanks for answering my question in part II.
Can you give us the low down on what it actually takes to be protected with a single member LLC. What sorts of things are good to say in my optional provisions? What other forms like that do I have to file? BTW: I only know that optional provisions exist because my state's new business registry website popped up a section for me to write some shit in there when I was registering my business. Like a pro I left that optional provisions section blank because I had no idea what to say.
After reading a bunch, I'm 100% sure I'm fucking up somehow and my business is doing jack shit for me besides providing me with an EIN.
Any help would be appreciated
LLC's are a state entity, not federal, so I can't speak much outside of how LLC's are treated in my state. Some states consider single-member LLCs to be no different from a sole proprietorship, but most states give them more protection.
If you want to play it safe, I usually recommend using a standard C-corp over LLC, then electing Sub-S status to get the federal side involved. You can actually elect to be a Subchapter S corp even if you originally set yourself up as an LLC instead of an Inc, and that will give you some distinctive tax advantages at higher levels of income, but doesn't affect your state-level legal entity/protecion. As for legal protection, when it is single-member I almost always recommend people go the Inc route vs. the LLC route, but my state treats them pretty similiarly.
Assuming you're stuck with the LLC and don't want to start a new corp entity, the first step in protecting yourself is one you've already done, get an EIN. If the biz has property or vehicles it uses exclusively, title them in the LLC name. Sign all contracts XYZ LLC, by John Smith (vs. just signing as your personal self). I've known people in States that treat single-member LLCs like sole-props to actually add a 1% non-voting, silent "partner", just to get the extra legal protections that come up when you have more than one member. Overall though, the levels of protection afforded to single-member LLCs vary too much from state to state to provide a clear roadmap, but these items would be a good start.
