TG synthesis can occur in both adipose tissue and liver under the influence of insulin. now the two substrates required for TG synthesis are glycerol 3 phosphate and fatty acids, fatty acids are predominantly synthesized in liver but some of it can also take place in adipose tissue. glycerol 3 phosphate can be made in both liver and adipose tissue.

fatty acid oxidation can occur in any tissue that posses mitochondria( liver, adipose and muscle mostly) except brain and RBC.

Yes anomali is correct..

Think about VLDL, it transports predominately TG to tissues right? Where does VLDL come from? The liver...

The liver doesn't degrade TG though, in a prolonged fast TG is degraded by adipose tissue into 3 Fatty Acids and Glycerol.. They are both taken up by the liver:

Glycerol enters gluconeogenesis--> Glycerol-3-Phosphate --> DHAP --> Glucose

FA's enter B-oxidation --> Acetyl CoA --> Ketone bodies or
--> TCA cycle to provide liver with energy and drive gluconeogenesis
