I'm on my first play through as well, it's really a great game and amazing for a gba title, I Don't get a whole lot of free time so I usually end up playing about 20 minutes - half an hour in bed each night and what I think is so great about it is that it's always delivering you a fresh experience through each part of the game, while some of the random encounters can get a little repetitive, the gameplay as a whole keeps moving at a comfortable pace, a lot of other RPGs don't do this very well and you can end up reading for what seems like an eternity or going over the same ground, same puzzles etc.. Golden sun keeps it fresh and it makes you want to progress to the next part of the quest.
Don't over think it just relax and enjoy the game, if you ever get stuck try this Android app for a good guide/walkthrough, though the game is actually pretty straightforward
BTW if you didn't know this already, FAQr is a really great Android app for reading walkthroughs and guides on all games including GBA games like golden sun, I'm currently trying to figure out where I'm up to..
You can download FAQr and then use any guide on GameFAQs that you want.
I think there's an app out there for reading gamefaqs faqs.
