The most important thing to remember is to not allow your back to round. Keep it flat or actually arch it a little. This also applies to squats and the various rowing exercises. For deadlifts you want to keep the bar very close to your legs, even brushing your shins on the way up, and push from the heels.

If you start performing deadlifts you might want to think about investing in some lifting straps & learning how to wrap them around the bar properly. There vital, if grip strength isn't up to par. I also perform my sets/reps wearing just my socks, no shoes. You can get deadlift slippers (picture below) but I prefer doing them in socks.

Deadlifts will increase the strength in the Hamstrings, Glutes, Hips, Legs, Lower back/Erector spinae. You will also increase max applicable force to the pedals & speed endurance.

Heres me performing the deadlift...




lol...

Also take note of the alternating grip. This stops the bar rolling.

................

I was going to mention that in reply to your earlier suggestion about lifting straps. They should only be used when absolutely necessary. Using the alternating grip you can lift a lot more than you can without it. Avoiding the straps will help your forearms & grip get stronger.

When I started doing deadlifts (Heavy), I needed the aid of straps. I had to do additional forearm & grip exercises, until my grip finally got upto the point where I no longer needed straps. I still wear gloves though.

That's it right there. ^^^ You could afford to adjust your calorie intake to account for the energy spent doing upper-body stuff.

Lift-straps are a band-aid fix to a crucial flaw in your strength. I don't think they should ever be used by anyone for anything. Fix the root of the problem before trying to put a patch over it.
Also, have you tried lifting without the gloves? Can you use chalk at your gym? From my experience gloves have prevented me from lifting heavier weights as their bulk got in the way. Then again I'm a pretty avid raw lifter. Heck, I think I've only used a weight belt twice when I 1RM-ed out at 435lbs at ~165lbs back when I was 17! Now I'm a weak and fat 23 year old at ~195lbs with a three rep max of 385 and a 3 rep max of 285lbs on full back squats... Oh the joys of college and what it does to you.

Straps do have the advantage of being able to hoist more weight for reps without a loss in grip. Additional work on forearm & grip strength away from deadlifting need to be done if that is the case.

I have a home gym kitted out, so I can use chalk but I prefer to wear gloves for numerous reasons, blisters, comfort etc. Sometimes in the summer I will use chalk to dry up the respiration & sweat on my hands, but I still wear the gloves over the top. There are special bars which can be purchased which are much thicker & bulkier than the standard one & that bar is specifically used to improve grip strength, so the bulkier gloves could actually be a benefit.

I don't have an issue with the use of straps if non-use will prevent the lift from being completed. I do think they should only be used when absolutely necessary. But deadlifts are not primarily a wrist and forearm exercise, so wrist & forearm strength should not be the limiting factor.
