La hareky bro, Nepal ma chill garnu
 For para gliding, I am not sure about the price, but they will take you to the spot ( sarangkot ko dado ;)you dont have to worry about that.
 About bunjee jump, you can buy a whole package that includes ride to the spot and back to the place they pick you up. Dont know about the price here too. But they are having problem this time because the villagers want that bridge for their transportation. Hope nothing goes bad by the time you reach there.
Looks like you love the shot of adrenaline, try rafting if they offer but I think its too cold ;)
Ghandruk is another beautiful place to visit.

Most of the hotels around lakeside are affordable as long as it is not festival time ( like street festival). + tax lol;

I would suggest you to stay one more day in pokhara and visit chamera gufa ( north side of pokhara ) , davis fall  ( guess south side), and gupteshwar gufa ( next to davis fall). If time permits, you can enjoy sunrise from the sarangkot.

Just for you info: baglung buspark is kind of redlight zone of pokhara.

Clubs are not that good, but if you like to go club, there are few in lakeside area. Lotus/Magic  is good .  There is another called paradiso ( never been there so not sure about the name).  
I would rather go to "Busy Bee" and have fun drinking and listening live performance by local artist than clubs.

Have fun harkey bro,
