To hold the bolt with one hand, and stedy the tyre with the other while pulling towards and then how to tighten and straighten the wheel...he made it look easy...if it is only time will tell!

Vickster, I've been doing a bit of wheel/chain tensioning these last few days and it is definitely something that will get easier with a bit of practice.
I used this video to get the basic idea, used the stand like in the vid but I'm sure it will still be useful to see if you are turning the bike upside down instead.

Ps- The guy is a bit eccentric but seems to know his stuff

Also tried a new tyre lever that helps replace the tyre as well as getting them off, certainly helped though you still have to be careful not to trap the tube.

.....and especially if you are riding fixed, make sure you check it, (and the wheelnuts), regularly.
