Welcome to R2R! You're definitely going to get some great suggestions and tons of help from everyone here!
Remember, there are tons of options for everything! You're already on the right track doing your research. Here are some suggestions that worked great for me:
1. Refugium Starter Pack. Algae Barn makes some great products to get your tank cycled and fuge up and running.
The Ultimate Refugium Starter Pack comes with everything you need to cycle, set up, and seed your refugium. Free Shipping & 100% Alive On Arrival Guarantee!

2. Clean up crew. Some great packages on Reef Cleaners.

3. Return pump. You're going to want something that does between 600-1000gph (general rule of thumb is 5-10 times tank volume in gph). Also suggest something that does more so you're not running it at 100%. I like running around 60-70%. Running two returns in case one goes down is also an option.

4. Powerheads. Flow is a tricky thing. You're going to want to make sure all corners of the tank and the behind rock parts all get enough flow to keep gunk from sitting. You just need to decide if you want wires in the tank, out of the tank, and what type of control you want. One plus side of getting products from one company is they can often all be controlled within the same app. Two decently strong powerheads + your return will probably do the trick. A third for circulation is probably options.
5. Skimmers. Reef Octopus is a fantastic brand and has great units that will fit in your sump. This is another area where bigger can be better. If you get one rated for a slightly larger tank, you're going to have better control over export.

6. Heater. 3 Watts of heater for every gallon is pretty standard. Look for a 300 Watt. Eheim Jager is pretty popular. I went with a Hygger because it can mount horizontally within the sump.
Again, these are all just things that have worked well for me. Others will have different suggestions that are just as great! Take it slow and find the products that work for you. Good luck!
