Thanks to all for the great advice offered in my previous post

We have decided to take Heathrow Express- just bought the tix with the 14 day discounted price- wish I had made this decision earlier- but oh well.
Our flight is actually at 9:50 (I had that wrong in other post). Aer Lingus to Dublin, Terminal 2. We will be checking bags
Plan is to take a cab from our hotel (near Earl's Court, above Cromwell Road) to Paddington and catch the 6:25 Heathrow Express, getting us to LHR by 6:40. That is just 3 hours preflight time- is that going to be OK?
What time would you recommend getting into a cab? I'm guessing 5:30? I know uber is also an option but we are not uber users (yet) and from what I can tell the cost diff is just a few pounds.
Thanks again
