1. Backpacks can be renamed.. Just open the pack from your inventory and then click on the 'i' in the top left corner of the packs window and select rename, easy and sooooo useful as it make organizing your stuff a breeze. It can also be used to create joke links for the chat windows.. see how many people fall for the "Ehmat's Twenty Slot Belt" and sending them on quests for it can be even more fun
2. If you're short that 1 skill point for that new piece of equipment then look at your base stats (strength, agility, intelligence etc) and try and boost them with IPs or buffs. All skills are effected by two stats and buffing the right ones can squeeze that last point.
e.g. Vehicle air is affected directly by Agility (20%), Intelligence (20%) and Sense (60%) so buffing those three skills (sense in particular) will get you those tricky last points.
3. Getting swamped by baddies cos some idiot decided to bring the dungeon boss and his henchmen out for a stroll? Try 'mesmerise' nanos, ok they're only available to Bureaucrats, Nano-technicians, and Traders. Great for turning that disastrous bloodbath into easy XP.
