First things first, you should get all golden treasure from EoC 1, 2 and 3. They will help out immensly, and will stay with you forever.

Next the levels you should go to is ItF, and complete at least Ch. 1, and get all gold as well.

While doing so, you should do a bit of SoL, but don't go too far in, as it'll get much harder later.

As for your units, I'd recommend neither any of them, as they are too situational at this moment.

Remember not to sell them, though, as they'll still help out later. Sweet XP is your best bet for grinding XP, and as you get stronger, you can tackle the harder stages, which will give you more XP.

Feel free to ask more questions, and I hope you do well!
