What made me think you weren't quite ready is that, in my opinion, DJing is a state of mind. It's about confidence and personality as much as anything and you come over as being a nervous wreck. As a DJ, you need to think on your feet - if things aren't going to plan you need to be able to think clearly enough to be able to alter what you're doing and change the course of the night. I think, maybe your nerves might get the best of you.
You come across as sounding very negative about your equipment and that is making you worse. When I started, I had a SoundLab powered mixer (the G742 - I've had it modified and still use it today!), a pair of Kam 12" speakers, a 4-head Acme Smart Gobo light effect and two moonflowers I bought from Woolworths. I also bought a smoke machine there but, to be honest, it was fairly poor when compared to todays even budget machines. But the thing I wasn't short of was confidence. I was a really nervous and shy person in day-to-day life but, when I was DJing, I thrived on those nerves and I came out appearing really confident. And that's what got me to where I am now - knowing how to convert the nerves in to positive confidence. If you can learn that then you'll get throught your night and, maybe, want to take it further. Or it could put you off forever!!
As for the kit you mention, with the exception of the Homemix (terrible unit, in my opinion - Argos have a lot to answer for!!) you've got enough to get you through a small show. And you're only playing background to a dancefloor so you won't need to raise the roof. If you've got enough CDs to cater for any requests then maybe someone could loan you (or hire at a small fee) a pair of old-but-reliable CD decks and a small mixer. Don't over-push the Skytecs and then you'll get through it.
But remember this - kit doesn't make you a good DJ but experience and practise does. You'll not learn this art in 5 minutes!
