I obviously do not know you at all but I would say keep going with your chavrusa and your shiur but try to dedicate time learning a masechta on your own without using Artscroll. I say on your own as you have already mentioned that you have time constraints so learning on your own keeps things flexible. Also learning on your own will allow you to focus directly on the area that you are aiming to improve on, namely, reading / translating skill.
You will find that if you stick to it, your skills will improve drastically over a few months.
I mentioned not using Artscroll so that it shouldnt become a crutch but as the same time there is nothing wrong with using it to look up translations. As long as you are genuinely trying to learn from the actual text and build your skills.
Hatzlocha!
