Send me this but in english

Lessons say lo que expands/gives more info on some idea expressed in the same sentence, and que= a noun.  I get that que=that restaurant (noun) but with lo que:  "Aquel restaurante, que/ el cual / lo que (I put-wrong)  Al recomendó, tiene unos postres exquisitos.   It seems that lo que expands on "that restaurant" by giving more info about it with: "it has some exquisite desserts." I did the same with "Tengo un sillón en casa que/el cual /lo que (I put-wrong) está sucio."  With "is dirty" giving more info/ expanding on the chair. Is there a different way of explaining that might click with me?

Is there a general rule about when the definite article must be used? Eg, in this exercise why does ‘fortuna’ not have one while abundancia, prosperidad and economía do?

Can I say bien interesante here? Also, why isn’t regreso a casa correct? 

Apparently this is standard Spanish, but in Caribean Spanish it isÑ

!No me encuentro/no encuentro   las llaves del coche! is the test item.

The correct answer is reported to be no encuentro.  
Encontrarse is said to be used when "surprised to discover something".  I interpreted the exclamation marks as indicating surprise at discovering I was unable to find the keys.  I was probably overthinking it, ?verdad?

I have heard that -se is literary and rarely used today.
