Wide Angle Lens feedback and Must Hit spots for upcoming trip

I'm traveling to Dublin Ireland and London England in the next few weeks for business and taking a few extra days of vacation time for London.  I'm lucky enough to be able to bring my gear on this trip and would appreciate feedback on the must hit spots particularly in London.  I may have one day within Dublin to take pictures as well.

I'm taking my Canon 5D with:

• 35mm ƒ/1.4
• 17-40mm ƒ/4
• 24-70mm ƒ/2.8
• 70-200mm IS ƒ/4

This means I'm leaving at home:

• 24-105mm IS ƒ/4
  
• 135mm ƒ/2
• 50mm ƒ/1.4
• Teleconverter 1.4x

I've gone back and forth on the 24-105 vs 24-70.  The widest I have is the 17mm-40.  I had been thinking about getting the Canon prime 14mm ƒ/2.8L II but it's sooooo damned expensive.  Yet, its not like I've been to London before.  Any thoughts on my loadout?

Secondly, I'd appreciate advise on the must see spots in and around London.  My wife and son will meet me in London so it's not a 100% photo walkabout.  

Thanks!
