For multi-table tournaments, I find
Tournament Shark to be very useful.
Holdem Manager is also an excellent piece of software, although it is more useful for cash games. If you are primarily going to be playing single-table tournaments (aka sit-n-gos or SNGs) then SNG Wizard is a good option. I haven't used WizHud.
Paddy Power is iPoker if I am not mistaken, and should be fully supported by Hold'em Manager. Hold'em Manager is allowed on all the poker sites that they support, so any feature that they include is allowed to be used on the sites that they supposed. Or did you mean Idle Miner products? I am not sure if those are allowed.
