I will suggest you take a look at Haryoh's Guide to RG, it has very detailed intruduction on the stats build, skill build and gears for different types of RG. I use this guide when I was newbee and find extremely helpful. Also I will suggest you go through all RG skills on irowiki so that you are familiar with them.
It will also be helpful if you can tell us what kind of RG you want to be. Gears and Skill builds for PVM and WOE RG can be different.
Based on your current gears, I see you are building an agi-crit Paladin. However you are not investing Luk at all, so it looks weird to me. I would say before you max out Overbrand, stick to this set of gears and build. Agi-crit is a viable leveling method for RG before you get to Overbrand.
So no matter what kind of RG you choose to be, Overbrand is a must as it is your main leveling aoe. So after you change job to RG, put all your exp into job if you are VIP. Max out Overbrand is your first priority. The other skill you definitely need to have is Shield Spell Level 1. You want the atk buff, which gives you the same attack as your shield Def.
I think the best weapon for Overbrand is Hunting Spear. Cheap and have high attack. Best Shield for Shield Spell 1 is Rosa. Cheap, High Def and Lighter. I will suggest get a couple of Hungting Spear and Rosa Shield and card them with different racial damage increase/reduction cards for leveling purpose.
You skill build for Pal is good. There's no waste skill. The other skill you defintely want to get is Defending Aura. Excellent skill against range attack.
Everything above are quite general for all kinds of RG. Others depends on what you want to do
