I've made a balanced LF II/LF III transition savefile which is both full (I have done everything which won't be possible to do in LF III), and down-to-earth (the main characters aren't even in the 90's, let alone at level 99).

All the characters are between level 60 and 83 (I intentionally killed Random before every grinding session, so he wouldn't hit the 90's in LF II).
Random and Cocka-Cocka have more than 10000 kills.
I have about 270000 GPs (which means in the 10th chapter, Wendie and her party will be able to take 27000 GPs for their journy around Wendie's former masters' residences).
I have a plenty of healing items and permanent boosters (including 99 Crystal Pears, which equals a reserve of 495 HPs).
There are also some rare weapons and pieces of equipment, such as Drosorium Axe, Demolition Axe and Gaes Ancient Horn. Each type of the Vahla weapons is a part of the inventory as well.
I avoided losing the Garden Key by not opening the gate in the castle garden in early 7th chapter, so the Thieves' Guild's quest will be possible to complete.
I've won the ArenA tournament only with Random and Askhbar (to get Inverness Bracer for Luci), since there will be at least one chance for everyone to participate the tournament in LF III with much better equipment.
As for LF II sidequests, I haven't completed the Destroy the Pit quest (Q197) and the Locate and Destroj Sacjdil Torture Organisation quest (Q165), because in LF III it will be possible to disarm all the trapped chests with Seiman, and once those quests are completed, those locations aren't accesible anymore.
