I believe you guys can make reads multi-tabling, however, it's better to start with 1. If you cannot read 1, you cannot read 2, 4, or 8.

On thing I like to do (I don't use a hud or have PT open) is, especially after I see a guy playing tight, I do a "find player" on him. Even if I know NOTHING else, knowing a guy is playing 4 tables, 8 tables, or _12_ tables is very useful. At 12 tables, only some kind of starcraft freak can do anything but play on autopilot (not that they can't make good money playing on autopilot).
