Well for general riding to the shops, jumping kerbs and kicking around I like to use these wheels:

They are 451, which as the long-timers on this forum know fit well on the swift, you just need new calipers.

But seriously, I'd suggest first step to new wheels is to decide if you are happy with the top gear on the standard bike, or if you think you need to use the capreo hub. The capreo hub gives you a 9T smallest sprocket which is a 20" increase in top gear and therefore can give you the same range as a 26-27" bike. It's a special hub size and special sprocket, although hub manufacturer 'Chosen' now make a quality cartridge bearing version of the capreo hub as an alternative to shimano's cup-and-cone bearing original capreo hub (that I have). Another advantage of the capreo hub is that you get round the problem of the chain rubbing on the chainstay in top gear - if you try and get higher gearing by having a massive chainring, then the chainstay rub problem gets worse. Advantage of having standard hub is that you can use a closer-ratio cassette (i.e. with a double chainring) that lets you use a shorter chain with more even tension and reduces the change of chaindrop. I've used capreo for a couple of years very successfully but I wear through the cassettes very quickly and you can't replace single sprockets like you can with a standard cassette. I am currently trying to make a standard hub/cassette work by going for a massive chainring instead. I've not cracked it yet - still blighted by chaindrop but I've not given up and next step is to try a front mech and double chainring.

Next is to choose spoke count. I've been doing a lot of research on this lately and it would seem that 20 spokes is enough for normal weight people, and less spokes doesn't help much anyway.

In terms of rims, sun, alex and velocity make 406 and 451 rims. Bontrager used to make 406 rims (maverick) but not any more. Velocity look the best to me, with the fusion or aerohead being the light and aero choices IMO. Sun's llightweight 406 offering is called M14a or something similar. I would avoid the lightweight alex rims if you can as my R390s cracked after just a year.

I was joking about the carbon wheels above but if you do want pimp then hed make their jet 50 (50mm) deep section carbon rims in 406 which do look great. They are really a carbon fairing over an alu rim but many of the best carbon rims are built this way.

I presume you want to go lighter and faster otherwise you would just stick to the stock wheels which are perfectly fine and I've been happy riding on them since my Alex/Capreo wheels broke.

I have under my desk a pair of wheels from a Dahon MU EX - one of the pimpest 406 wheelsets you can get. I am going to be testing these as soon as I get a dry evening at my local velodrome (I have to give them back to dahon in mint condition) - or rather I'm going to be testing just the rear wheel only as the front hub on Dahon's is 70mm and Swift is 100mm. Even so, if there is any efficiency advantage to having only 14 paired bladed spokes and a light aero rim, then my test will measure this to the nearest couple of watts, compared to the stock wheels.

Velocity also make wheelsets, such as the thracian and uriel wheels (fusion rims I think). These wheels look good but my opinion is that the whole paired spoke idea is just a trend/fad and one that we are already moving away from.
