Stand, type, QNH please - that way I record them on the strip so when you make your later later calls for start/push/taxi, I know where you are and don't have to give you the QNH - if it has changed, I'll generally give that with the taxi clearance as "new QNH". It's also one less thing to read back - with the holding point, runway and "cross runway 12" if we're using 24 here, that's more than enough!
I prefer the call for clearance prior to start/push, as it allows me to issue it when I've got time, rather than needing to do it during the taxi phase, or when approaching the runway - with the associated risks to do with runway incursions etc.
Please note we only get your squawks 15 mins before the EOBT (estimated off blocks time) now, so a call made earlier than that may result in clearance with no squawk, or just being told to call back later!
