1) Yes, you may draw your tree without using an outgroup.

2) In any phylogenetic tree, outgroup is the one which is more distantly related group of organisms that can serve as a reference group in order to determine where in the evolutionary history ingroups stand. Now you may understand what effect does an outgroupo bring to phylogenetic tree.
