Spectra tow rope is top end $$$... There is one in the I boats store for like $70ish. There are low stretch in the middle ropes you might wanna try first before dropping coin into a sport your first starting, just don't use a ski tow rope.. They are spongy.
Board 144-146cm for your weight ( stance is something you need to play with) I'm 6'3" and 205. I ride 15* duck foot regular and widest stance possible. As for brands, when your just starting I would suggest a continuous rocker board or if you plan on trying to advance a "hybrid rocker"- mix between continuous and 3-stage so you don't slow your progression and grow out of your board in a year. Don't buy a full 3- stage until you get more comfortable and edging is good toe and heel. Also a board with subtle molded in fins and removable center fin. The center fin is for stability, but inhibits surface tricks and once removed allows the board to become slippery. I started with an O'brien from BassPro, just your basic package $200 and rode that for a year. Then I bought a liquid force trip and CWB Answer closed toe bindings ($500 setup), it was a night and day difference and rode for 2 years. I'm now on a full Ronix One board and bindings combo ($750) and its by far the best thing I've ever rode.
Bindings( personal preference, see what is most comfortable... Open or closed toe) side note: wakeboard bindings won't release your feet like skis, plan for abrupt stops if you catch an edge. Open toes are most likely to release if you fall bad enough to lessen the impact, closed toes are more responsive for edging but I've never had them release on me. I prefer the latter of the two.
Boat with enough power to not drag you through the water when getting up.
Watch some YouTube videos on how to get up and beginner things. Ollie, riding switch, heel and toe carving, surface 180*s. "The book" is excellent, but not really necessary unless you want to get more serious.
Hopefully this helps some.
