Get out there, perform as much as possible to as many different people as possible, and use that time to practise managing your audience's attention.
I do a trick where at one point I need to secretly load 3 cards which are sitting in my pocket into a packet of 4 cards which I'm holding in my hands. I spend ages figureing out a covert way to do this, but after a few performance trials I realised that the simplest option was to simply create a situation where they wouldn't be paying attention. The trick is one of the strongest FASDIU tricks that I know do.
So, if it is possible to reach into your pocket, grab three cards and load them into a packet without anyone spotting it, then it is definitely possible to take your techniques out on the road - if they are at the point you say they are.
With regards to your comment about "I have to be talking about the deck at the time", I do not believe that that is necessary at all. Everything important should be done on an offbeat - you really don't want to be executing sleights whilst calling attention to them. It really is so easy to create an offbeat, there's no excuse for not using it. Make a funny comment, address a question to one of your spectators (use their name!) etc. - do the move then, THEN call attention to the deck. Or do it after. Sleights are not time sensitive, so long as they go in the right order and all.
Happy performing!
