TAP are actually OK as an airline. Their fleet is pretty modern and the crew are usually very professional but also very nice. As a company, they do unfortunately tend to shoot themselves a bit in the foot with their customer service when things go awry, which is why you'll see a lot of people saying never again.
Assuming your transatlantic flight is with them too, there'll be decent seat-back entertainment on your transatlantic flight and, depending on which aircraft they use, you may get free wifi messaging (whatsapp and FB messenger, text only, no images).
You'll also get food. On transatlantic flights you'll usually get a main meal shortly after boarding and a snack shortly before arrival. I think wine is free with the main meal but not 100% sure, as we don't drink alcohol, but soft drinks and juices are definitely free with the meal.
The bit with the bags is normal for TAP. I didn't realise that's who you were flying with or I'd have alerted you to it.
