I am farming Jelly Gems and have a setup like.......This!
Weapons: Fireburst Brandish OR Super Blaster-(the jellies in Stage 1,2 keep KILLING me) ; Nightblade
Armor: Dusker Set
Shield: Horned Owlite Shield
How's it? Please suggest something better than this.
Thanks in advance
Your setup is fine, although a piercing shield would be better than an elemental shield. And there is even a piercing shield that gives your swords a damage boost: the Barbarous Thorn Shield line. So get that, as Traevelliath says.
Much of this has already been explained to you, for example here and here. Be sure to read the help that players give you, or they may stop giving you help.
Enjoy the game.
Your shield is fine as it does resist the elemental bullet attacks that are present on the levels, you just have to play in such a way that you only need to tank those shots. In your case, this would mean becoming more of a ranged fighter that occasionally runs up and swords them to death when the opportunity presents itself.
Alternatively, barb thorn shield would make the most sense to get for when it comes to tanking the bulk of damage from slimes, and would let you use your sword on them consistently. The damage boost, especially early on, would also be pretty nice.

Your armor and weapons are great. It may help you to use shadow damage to fight the slimes, but it really isn't necessary.
I have thought of a strategy in which I use one gun like the Elemental Blaster or Dark Chaingun and use it to kill the jellies long range and then charge my Fireburst and blast them to hell.
Or I get a Graviton Charge and then charge my swords after trapping them in the Vortex.
Please suggest the better one out of these two at my level ( 3*).
Thanks in advance
Both of those strategies work. The vortex strategy works much better in a party, where there is one vortex bomb and a couple of people charging weapons into the vortices.
The gun strategy makes more sense if you gun on approach and then do sword *regular* attacks. Because if you're doing sword *charge* attacks, then while you're approaching the monsters you should already be charging your sword, not gunning them.
This is what makes the brandishes so powerful. You run up to the monsters, release a charge attack, and run away while you charge up again. Whenever you're near the monsters, you're releasing huge amounts of damage, status, and knockback. They don't stand a chance.
So another strategy is to skip the guns and the vortex bombs and just charge your Fireburst Brandish at the monsters. You can definitely beat all of Royal Jelly Palace using just that one weapon, and not even very slowly. If you're solo, then this is probably more efficient than trying to charge into vortices.
I don't think you could pull off the vortex strategy very well, especially when alone. You'd need to have more charge time reduction, longer suction on the vortex that you'd get at four and five star, and possibly a build that could transition into granting you movement speed to negate the movement decrease on your vortex when you rolled enough charge time reduction onto it. While keeping what you'll become at five star is important, having a build that starts out strong, ends strong and lets you "just fight" is also helpful. If you really want to be a vortex bomber, start with demo armor and roll for CTR med to very high on electron or graviton bomb, using your gun to finish off enemies that are weak and bomb for crowd control.. then transition into mercurial demo.
Starting loadout:
Spiral demo set
Some defensive shield; probably plate or owlite+dread smelly
Electron/graviton bomb, fully heated, not charge.
Blaster
Ending loadout:
Mercurial demo set
Defensive shield
Bomb CTR trinket
Optional Sword CTR trinket
Obsidian crusher + Electron vortex (MUST heat to level 10 for CTR AND get at least CTR med)
Optional Combuster/Acheron with CTR med+
Valiance
But really you're better off just using your brandish and mastering the basics without trying to be a bomber. Bombing with this loadout would force you to play well with others which is a good practice and would leave you much stronger than your current loadout, but it would take longer and be relatively frustrating for you. For instance, the reason mercurial demo is viable here is because of how long you'd be taking to get through the game in the first place.

Tl;dr just use your current setup and go spam your brandish until you're 5* and then some. Which is what we've been telling you for some time now.
You're going to want a better shield and/or a pierce resistant shield. Since you're a swordsman, the best option is the Bristling Buckler line. The recipes can be either really expensive on the AH, or hard to find in the clockworks, but it's one of the best shield lines for swordsmen.
You might want to consider Nightblade + Elemental Gun, like the Elemental Blaster or the Pulsar. Alchemers could also work, but they tend to be rather underwhelming until about 4*.
