Connecting sentences with more than a single verb?
So, I'm able to make single sentences like - I watched TV, I watch TV. I like chocolate. etc
But when I have to put more words in and more than a single verb in, I just don't know how - since it's not the same as in English.

If anyone could help dissect and write these sentences for me, pointing out any patterns to write similar sentences, and any tips I can use. Basically, how to put more than a single verb in a sentence.

I sat and watched TV,
I bought and read a book,
I ate and drank in the restaurant.

I loved his dancing
I needed to study
I helped my dad cook.

Thanks for your time, you don't have to do them all, even one will count as a good contribution!

Answer

You can use particle 어/아 to connecting verb and verb when the actions are sequential. The tense of first verb is usally omitted.
아 is used in cases when last vowel of verb stem is ㅏ or ㅗ.
어 is used in the other cases.
서 can be used after 어/아.

You can use particle 고 to connecting verb and verb when the actions are at the same time. The tense of first verb is usally omitted.

I sat and watched TV. 
앉았다(past tense of 앚다) + 보았다(past tense of 보다) 
=> 앉(다)+아 보았다 => 앉아 보았다.
나는 TV를 앉아(서) 보았다.

I bought and read a book.
샀다(past tense of 사다) + 읽었다(past tense of 읽다) 
=> 사(다)+아 읽었다 => 사 읽었다.
나는 책을 사(서) 읽었다.

I ate and drank in the restaurant.
먹었다(past tense of 먹다) + 마셨다(past tense of 마시다) 
=> 먹(다)+고 마셨다 => 먹고 마셨다.
나는 식당에서 먹고 마셨다.

If a verb is used as an object, the pattern is ~하는 것을 ~하다
I loved his dancing
나는 그가 춤추는 것을 좋아했다.

I needed to study
나는 공부하는 것을 필요로 했다. 나는 공부를 해야 했다.

I helped my dad cook.
나는 아버지가 요리하는 것을 도왔다.
