Take it you've ridden "real" trials before? Getting all that dialled in first will help a lot. The moves most streety things seem to come out of are, as said, manuals, bunnyhops and 180s (which you can turn into 360s with practice and spinning a bit faster). Just get out and play really, see what you can do and watch videos for indpiration. Obviously there's Danny Mac, Ali C and co but i find most inspiration from people like Joel Bennett, Phil Feeney, Mark W of this parish, Ben Rowlands, Boon and Rowan. All got a nice creative style and definitely gives you a few ideas!
As for manuals, concentrate on finding your balance point. Intentionally loop out a few times and you'll get to feel where the bike will sit comfortably and where it's gonna throw you off - just remember to be ready to step off the back! Get your weight right over the back wheel and you effectively sit into it, getting your arse right down low. Imagine leaning back and sitting down in a chair, you're doing that motion just without letting go of the bars. Arms straight, and use your legs control it. One thing that really helped me was consciously forcing yourself not to give up, i always used to get scared and pull my back brake mid-manual, but instead of that, i now think to myself "bend your legs!" and it'll bring the front end down and carry on rolling. Trya nd keep the front wheel quite low too, if you want to manual brakeless, it's a lot easier to control and helps you progress onto bunnyhopping from a manual, using the preload you've got going on to give you the pop but not being so high you come off the back of it. That's another thing actually, try doing a bunnyhop to rear wheel, but never hopping out of that first pre-loaded position, just before you would launch your body upwards.
Just get out and ride, have fun and see what happens
