The next sentence is a lie because it is not a sentence, it has no verb. So, the first sentence is also a lie because there is no 'next sentence'.

I'm going to begin to study paleontology next semester.
A semi-colon denotes the end of a statement. If you omit the semi-colon, the statement will extend into the next expression and this will result in a compiler error because a semi-colon will have been expected at the end of the first expression.
The man next door wasn't very stable on his feet, he was a doddering old man The preceding is a run-on sentence (comma splice). You need a semi-colon or a period between "feet" and "he."
Before I begin my next surgical procedure, it would be a good idea for me to bone up on it.
The subject is aunt because the rest of the sentence is about her.
"Around the next bend" by itself is a prepositional phrase. It cannot be a sentence by itself because it has no subject. In a conversation, a subject may be implied, but that does not make it a sentence.
I don't know if you're asking if quotation marks should be used to begin a sentence or if you're asking if a sentence should be started with a quote from an outside source. So I will answer both. Quotation marks may begin a sentence at any time necessary. While writing essays, in my experience, professors like a little introduction before a quote. But there's no rule saying you can't. Maybe in the sentence before the quote you write an explanation then end the sentence and start the next with a quote. But you could most times use a colon instead of ending the sentence and then the quote would still be within the first sentence.
In journalistic writing, only one space. In all other writing, two spaces.
Would it be a sentence or a phrase? If a sentence, no, it would be incorrect. If a phrase, yes, it would be correct. I like the phrase!
Read your sentence out loud-- only what you wrote. Is it a complete sentence? Or, is the other half in the next sentence? Does the sentence have a subject and verb (actor and action)? Stop after each period-- if you have to ask "What then?" or "So what?" or "because what" after a period, you might have a sentence fragment.Example:Fragment: First sentence - He was going because. (because what?)Fragment: Second sentence: He bought tickets.Full sentence put together: He was going because he bought tickets.
