Hey bro, thanks for visiting the Q/A and reading the work I'm putting together here. First off, lets talk about your food intake. At your height and weight, i think you can handle a good deal more protein than you're getting. I would focus on getting about 2 grams of protein per Lb of lean mass. My suggestion would be closer to 350 to 400 grams a day. From there, I'd start with about 300 carbs and 100 grams of mostly healthy fats. If that works out for you and you don't see yourself getting fat, I would add in more carbs and fats. Try to taylor your diet around the protein though, keeping it up high. 

For your next cycle, I would keep the test at the same dose. Honestly, even if you only added in the dbol, you would upping the total mg of hormone for the cycle, so I wouldn't see a need to add more test. Considering that you want to add dbol plus another hormone, the test is just fine where it's at. You will be going from 500mg EW in the first cycle, to about 1 gram of total hormone in the next cycle. I dont think this is overkill, but I certainly would keep the test where it is. Both EQ and Deca are great compounds for their own reasons, but if you want all out mass, Test/Deca/Dbol is a classic mass building stack. Something about the synergy of these compounds together work very well. If you split your dbol into 2 doses a day, you should be fine. If you really want to split hairs, 3 doses will keep your levels more stable. Be aware that dbol has a high conversion to estrogen, so you may need a little more adex while running it. DO NOT use nolvadex on cycle with deca. Believe it or not, this can actually create gyno issues. So rely on your AI for estogen control. As it is, you really dont need nolvadex on cycle, if you are using an AI. Also, be aware that Deca can shut you down harder than many steroids. You may want to consider using a low dose of HCG through the cycle to help you bounce back quicker. I'd run the test just a little longer than the deca, as deca has a longer life. And one more note, now days, I will run longer cycles and switch test esters throughout, but I found that when I ran 12 wk cycles, I liked to change test esters on each cycle, so if you used test e, I would personally use Test Cyp this time around. If you don't switch, I really dont think it'll be the end of the world. It may not have made a difference for me, but I felt like it did, mentally ;)  Here is how i would outline your cycle :

1-14

Test 500mg

adex .5mg 3x wk (more or less as needed, just dont take too much and kill all water retention)

HCG 250IU 2x wk

1-12

deca 400mg

1-6

dbol 30mg

PCT starts 2 wks after last test shot
