I know that last question wasn't directed towards me, but I've always been partial to blue green chromis, any type of clownfish, bicolor blennies, neon gobies, six line wrasses, cardinals, hawkfish and other small wrasses and gobies.
You need to research your fish online or purchase a pocket expert guide before starting to make fish purchases.
Some fish don't get along with others, some do get along but need to be added after others. Some fish have certain needs like sandbeds, certain dietary needs among other things. So, research, research, research.
If you're going with fish only for the time being, I don't see a problem with you waiting on the skimmer, but I would keep it near the top of my list for future purchases, especially if you plan on putting coral in at some point.
You asked about fish suggestions: If you start putting in puffers and triggers and that sort of messy eaters then you're going to have dirty water. If you're sticking with small, reef-safe fish you should be fine as long as you don't over stock. I've always liked the 6-line wrasse, clownfish (the maroon and gold stripped is one of my favorites), bicolor blenny, dottybacks, there are many varieties of gobbies that are great. Just do the research on what each fish needs and you'll be fine.
