To tape and mud drywall, use a drywall knife to spread a liberal amount of drywall mud into the seam between 2 drywall boards, then run the trowel over the freshly-mudded sections.

Don't mess around with a drill or power screwdriver. Borrow a drywall driver or invest in a counter-sinker designed for drywall applications that attaches to the end of your drill. These tools perfectly countersink every screw you place if you drive them straight. Make sure your screws are correctly countersunk. You want the screws to lightly dimple but not tear the paper coating of the drywall. Minimize "butt" joints. The long edges of the drywall are tapered; the short edges and any edges you cut are not tapered and will form "butt" joints that are more difficult to finish.
Make sure the corners meet the same way, but don't worry too much about larger gaps — as long as the sheets are attached solidly any gap can be filled later with setting-type joint compound. However, keep in mind that tighter joints makes for a better seal and will also make the floaters jobs easier.
Schedule an inspection, if necessary. If your local municipality requires an inspection before mudding your drywall, schedule the inspection. It's better to be put through the inconvenience of scheduling a walk-through than having to tear the whole thing down after you've taped and mudded your joints.

On the first coat, On inside corners: Keep one edge of your blade running firmly against the drywall on one side and lightly against the tape on the other side. On butt joints: use the drywall as a guide for both edges, leaving a convex curve On taper joints: same, only leaving a concave curve. Get the right mud. You can buy a dry mix just add water or you can buy ready-mixed mud.
Both come in different mixes, such as lightweight easy sand, quick setting, or standard grade. The dry mix is cheaper, and you can make as little or as much as you need providing you're clear on how much you can apply before it sets up.
Use it to fill big holes and gaps. On larger surfaces it's generally harder to apply, harder to sand, not as smooth, more time consuming, and a bigger mess. However, it sets up chemically setting times vary; look at the bag and so will be ready to re-coat sooner.

Use the "all purpose" mud for your base first coat to seat or cover the tape, and lightweight mud for the final coat. You can also use what is called brown or topping mud; it's actually beige and dries to a very pale color, and has a more plastic texture than regular mud.
It dries smoother, has less of a tendency to bubble, and is intended for the final top coat. Avoid mixing speeds that are too fast, as you make create air bubbles in the joint compound.

Use a bright light held at an angle to better see the tapered area that must be covered. As you draw the mud and blade down the wall, sharpen the angle until the blade and the wall are nearly parallel.
Smooth out the compound. When all the seams are filled, make a single pass over the freshly-mudded sections to smooth out the compound. Think of the first coat of mud as the glue that sticks the tape to the wall; as soon as it dries it's useless.
And you have another project fixing it, probably after you think you're all done. So don't lay down more mud than you can cover with tape before it dries anywhere on the seam.

While this may make it a little easier to work with it greatly increases the mess and awkwardness of the tape when actually mudding.
