Cristiano - welcome to the forums!
Might I suggest initially getting a TeleVue 2x barlow and using it with your current eyepieces. This will effectively double your eyepieces. Bintel's site isn't clear, but does your scope's focuser accept 2" eyepieces, or only 1.25"? If so, I'd recommend this eyepiece:
2" 80
° UW 30mm eyepiece
which can be found here:

Just scroll down slowly from the top of this page and you'll find it. It's a bargain at $99. It's not optically the best eyepiece on the market, far from it, but it does offer really wide views, it's pretty crisp in the centre, and not too bad at the edges. There is some distortion, but any type of eyepiece like this, no matter who the manufacturer, will offer distortion. It's a real bargain at this price to be honest. You can see a review on IIS (Ice In Space) itself, here:

It's a nice ultra wide angle (80 degree apparent field of view) that is good for viewing wider nebulae structures, or just simply homing in on a target.
For viewing - my honest advice, if possible, go to dark skies. My recommendation is the national park out near Glenbrook (can't remember the name) - very dark skies. It's been a long while since I've been out there (15 years plus), but the SMC (Small Magellanic cloud) and LMC (large cloud) are easily visible from this location. You can camp there, it's not very expensive either, there's fireplaces available and some camping facilities, and also toilets. You could always go for a Friday and Saturday night viewing session. During the day, there's plenty to do - bush walking, photography (lots of wildlife - wallabies, kangaroos, galahs, cockatoos, lots to see). You can even travel a few kilometres to jelly bean and black been pools and having a swim in the warmer months! The water is very clear, very clean and a delight to swim in.
Hope this helps!
