Buying a tool kit

Just reviving this thread to ask a tool kit related question.

I currently have no tools. Just moved to London, and I have a fixed gear bike. I need to perform the following tasks:

• Remove cog & lockring for cleaning/maintenance.
  
• Install new pedals
  
• Adjust brakes
  
• Adjust seat post
  
• Check crankset (feels ok/tight, but would prefer to be safe)
  
• Install new brake lever w/ new brake cable
  
• Change tyre/inner tube
  
  

I know I need the following tools:

• Chain whip (will 1/8 and 3/32 be interchangeable in the short term? Or do I need 1/8 (I think my components are all 1/8).
  
• Lockring tool (for rear hub)
  
• tyre levers
  
• Set of allen keys
  
• Spanners (15mm, 10mm AFAIK).
  
• Cable/wire cutters (maybe... I could do a scruffy job based on the leatherman I have at home)
  
  

Based on the above, I've been looking at toolkits, namely these ones:
1) http://www.tredz.co.uk/.Bike-Hand-Bicycle-Maintenance-Tool-Kit-Shimano_41164.htm
2) http://www.tredz.co.uk/.Ice-Toolz-Essence-Tool-Kit_60194.htm

Which one would suit my needs better, or should I buy the items individually? If neither, is there a better starter tool kit?

Do you guys see me needing anything else if I've neglected from the above?

Thanks.
