I'll volunteer to be 101.
With the tank setup you have it would be more stable to add the additional liverock. Liverock and the crushed coral once it develops the proper bacteria will act as a filtering agent in your system filtering out the ammonia and starting your nitrogen cycle.
From you description it sounds like your filter is a simple floss pad with a biowheel. It's an HOB style probably a Penguin or a Marine Land? IMO remove the biowheel. They are nitrate factories and your tank will be better without it. I know it's scary and everyone else is telling you different, but that is what I would do. I ran a 18g, and a 44g for a couple of years using only the LR, and LS as filtration with a filter similiar to yours with no biowheel and no filter pad. JME
As for the rock, yeah I would get more. It might just be the picture, but it looks like much of the rock you have now is not LR, Is that the case? Marine is not like fresh, you can't just put any type of rock in there, some types will poison your tank.
On the stocking guide since it's your first tank, I would keep it easy. Those shrimp are going to be good. You could look into volcanic red shrimp as well. They are very tough and if you forget to feed them for a couple of years they'll be alive, not happy but alive (I'm serious on the years part, it's crazy but true, look into desktop biospheres).
If the tank is for your daughter I bet she will love the electric blue color damsle fish. They are a great beginner fish. Almost bullet proof and still have that fun and exciting bright color. They are kind of bullies though so housing them with smaller fish may prove problamatic.
Many types of gobies and blennies are easy to care for and great beginner fish. I'd stay away from the manderin gobies, and the dragnet gobies. They are lucious to look at, but very hard to keep especially in a 35, without some serious equipment additions. It is the fish that actually got me into really researching salt water, (after I had it and a seahorse, I was a dumb newbie) and started my addiction. Damm $10 fish cost me about $400 in equipment just to keep the pod life up enough to feed. So, I'd stay away, at least for now.
The carpenter's flasher wrasse is also a great beginner fish choice and very colorful. I would introduce these first to your system as they has a tendency to get picked on. Make sure you get one that is eating frozen mysis or frozen brine. Make the LFS let you watch it eat frozen, if they don't don't buy the fish. Some LFS's are picky about this, I find a handful of twenties and "I came to buy the fish, if you don't feed it infornt of me, I'm leaving," will persuade even the most persistent LFS owner. I have a luxury that I live with 2o minutes of about 12 LFS's so even if the fish does eat the ammonia will not have time to build up in the bag before I get the fish into it's QT tank.
Some snails are intresting to watch as well. I like the Top Crown Snails (aestrea endoza) alot. The bumble bee snails (Pusiostoma sp., Engina sp) are also very intresting. The Naussarius snails (Nassarius distortus) are also cool especially for kids because they look like unicorn snails ( jut say that she'll love it

)
These are just some of the options available. Different species of fish have different restrictions on tank mates. I would go to some sites like Liveaquaria.com for example and take a look around. Make sure you get something that can live in your tank. When you figured out what you woule like to keep, come back and post and we can help you with compatabilitiy.
Also back top your equipment for a moment. What kind of maxijet is that? If it is just going to be a FOWLR (Fish only with live rock) system, you might want to add another one. Maybe place it so the flow will go through your rocks once they are added. This will eliminate deadspots and really utilize the filtration of the LR since your filter is kinda on the small side.
Also to save some coin, you could buy lr that has been dried. It is usually much cheaper but will take some time to fully develop the aerobic bacteria. But if you don't mind stocking your tank slowly which I would really reccomend, then it is fine.
Good Luck
