How many tablets would go in say a 5lb batch of Brew? And when would you add the tablets in? When boiling the water for the wort?

Campden tablets, 1 tab per 20 gallons.

Since campden tablets seem to be suggested, would these be a good option?

Your recipe sounds like it'll turn out well if all goes according to plan! You may want to add some sweetness back if it ferments dry, but you've got several weeks to figure that out and read the Wiki to get all caught up on the method and terminology to things like back sweetening and nutrient addition schedules. I admire that you're being industrious with your fermentation equipment, I wasn't brave enough to start fermenting with whatever I had on hand with my first batch.

If you think you'll stick with it, here's the equipment I used for my first batch. I highly recommend looking into it if you think you'll do another batch! (I apologize if you aren't in the US, Amazon is my go-to)

• Hydrometer - $15.99 | You'll definitely want one of these first! It'll help you figure out when fermentation is done, plus it's nice to know your ABV when your friends or family ask "How strong is this?" (if you like to share)
  
• One Gallon Glass Carboy with Airlock, Drilled Stopper, Polyseal Lid - $14.81 | A glass carboy could last you forever! These have done very well for me, and the included airlock will give you a great setup for less than $15. The screw-on cap is just an added bonus, I use mine when I cold-crash.
  
• Star San 16 oz - $16 | This seems like the go-to sanitizer for the sub, and I use it as well. If you think you'll do several batches, I recommend going with the 32 oz size instead! It's much cheaper per ounce.
  
• Campden Tablets aka K-Meta (Potassium Metabisulfite) - $6.08 | This will help you preserve and stabilize your mead before you bottle. Some people don't, but it's highly recommended!
  
• Auto Siphon - $13.99 | This makes racking to secondary and bottling much easier! When it comes time to bottling, it's also really nice to have a Bottling Wand - $5.86
  
  All-in-all, this is just about my current setup excluding yeast, yeast nutrients, and extra carboys and airlocks. The list above comes out to about $127.45 USD before tax, which really isn't too bad considering one gallon should yield just shy of 5 standard wine bottles! Most commercial meads I've seen ranges from $15-$25 with some exceptions (There's a winery near me called Oliver Winery that makes a mead called Camelot Mead that sells for about $8 per bottle. Very good for such a cheap mead, you can probably find it at Total Wine & More if you have one nearby).

  Sorry for such a long comment! Best of luck in your mead-making adventure!
  
  Edit: If you have a local homebrew store, I would opt for that rather than Amazon. Prices may not be as cheap but you won't have to wait for shipping, you'll be able to support a local business, and employees at homebrew stores are usually really helpful and they can recommend recipes and give you pointers. Nothing beats face-to-face interaction!

Campden tablets. One tablet treats 30 gallons. Breaks chloramine down to chlorine and ammonia, both will dissipate. By product is potassium and Sulphur. https://www.amazon.com/gp/aw/d/B0064O9HWI/ref=mp_s_a_1_1?ie=UTF8&qid=1504447592&sr=8-1&pi=AC_SX236_SY340_FMwebp_QL65&keywords=Campden+tablets&dpPl=1&dpID=51SQGJPtqaL&ref=plSrch

So why do I need both since Fermaid K has DAP in it?

I was basically set on yeast nutrient and Campden Tablets. Is there anything else I should get?

Sorry. Can you give me a picture or a link to the product?

This is what they should be like: https://smile.amazon.com/Campden-Tablets-potassium-metabisulfite-100/dp/B0064O9HWI?sa-no-redirect=1
