Tomes might be easier to earn then you think. Most of the daily roulettes(expert, 70, 50/60, leveling, trials, mentor, frontline, alliance, and normal raid) pay a bonus in tomes if you run them at level 70. Getting with a hunt train on the level 70 mobs will pay out in creation and mendacity(along with centurio seals). You can get them running PotD or HoH. You can get them doing treasure maps and uznair runs. A single run of the level 70 alliance raid(you currently meet the requirements for royal city but not yet for the 2nd one) would get you 100 creation and 20 mendacity(plus a shot at 330 gear if any drops for your class - 8 chances per run)... plus another 100 creation and 50 mendacity if you got their from the roulette rather then a direct que. Putting together a group to clear the first 4 floors of the level 70 raid(deltascape) would not only get you a handful of tomes(like 10+5 per floor) but probly a few upgrades as well. It takes a little bit of effort, but not as much as you might think. And once your gear is caught up unless you take a break you stay caught up until the next expansion.
