I'm not familiar w. Warren Tools, but if price indicates anything, they seem to be better than "beginner" quality. Haven't found any reference to what steel is being used, or what the Rockwell hardness is, which would be more helpful in determining the quality.
Seems like the Warren tools are a reasonable starting point. The choice of handles will let you determine what feels good in your hand. But after awhile, swapping the gouges and blades back and forth will become tedious. By that point, you may know which tools are your favorites, and consider buying better ones of those. And/or buying several more so that you don't have to stop a carving session to re-sharpen. For instance, I have 3 of the same kind of Mora carving knives just because I like the way they preform for the types of cuts that I make.
Also, really inexpensive tools often have a hidden price, which is called frustration. As a beginner, frustration can exact a heavy toll. Nothing like botching a finishing cut because the cutting edge crumpled under pressure to turn a stick to "designer firewood."
For myself, most of the portable benches thew wrong height. For some work, I like a surface around 40" high so I don't have to bend over. For other work, like detail carving, I want a surface that is around waist height. A a result, most of my detail work is done sitting on a bench with a heavy pad over my legs, and a carving glove on my gripping hand, aka, lefty.
Also, think about sharpening. It takes some practice, but being able to put a good edge on any tool is necessary.
