If you’re in MA, the best thing to do would be to consider joining a local chapter of Trout Unlimited. It will take years off the learning curve. Most chapters have beginning fly tying classes, casting clinics etc, and if you’re new to fly Fishing, you’ll get a ton of advice about where to go, techniques to use, hatches, get to participate in group expeditions to local and further off long-weekend type fishing trips, and get a chance to try out different gear during informal casting sessions on the lawn before meetings. And you'll get a chance to try out gear owned by other tyers, learn all kinds of tying tips and tricks and get hands on help. You can use this link to locate a Trout Unlimited chapter near you:

As far as kits go, many of us started off that way. But you’d be better off sinking a few more dollars into a decent vise and tools and buying materials for a few proven, easy to tie patterns at a time. 30-100 dollar kits usually come with an 10 dollar imported vise (soft metal jaws, poorly machined parts), some inexpensive tools, and a small amount of a lot of different materials -usually not enough for the patterns you need plus other stuff that you won’t use. If you stick with tying, you’d likely want to upgrade everything fairly soon.
Depending on your budget, you could put together a decent to rocking set up to get you off to a great start. The difference between decent and great would be in the quality of the vise and to a lesser extent the tools.
If you throw out a budget, and the types of fish you’ll be chasing, folks can chime in with specific recommendations, but a ball park range is roughly:
Vise 35-150 with the lower end being no frills vises that you may want to upgrade for more functionality, but are sturdy and well made. At higher end are quality vises that you might be likely to move to anyway if you stick with tying. And there are many choices in between.
Tools 12-60 bucks. Musts are 4” scissors with fine point and a bobbin to hold thread. Bodkin, whip finisher, hackle pliers, hairstacker, bobbin threader are nice to haves . The quality of some tools- (scissors and bobbin) is more critical than others, some you can easily make yourself (bodkin, threader) others may not be necessary depending what/how you tie. For 12 bucks you could buy an inexpensive imported pair of scissors and a bobbin with a metal tube that you would want to upgrade soon. For 60 you could get a set of quality tools (essentials plus nice to haves) that would last a lifetime.
Materials- 30-40 bucks would buy 3 different 25 packs of decent hooks and materials to tie 3 or so basic patterns. For trout, say Woolly Buggers size 8, and Hares Ear Nymphs and Pheasant Tail Nymphs in 14-16. These patterns are easy to tie, use the same material for tons of other patterns, and most of all, they catch fish. You’ll have a lot of material left over after tying a dozen of each. If you were chasing other fish- bass or salt water, the patterns and materials might change, but the cost would be the same for 3 different basic patterns.
From here on out, you’d be adding more materials and a tool here and there as opposed to adding all of the above very soon after you bought a kit.
This recent thread, and the embedded links, might be helpful, and has some specific recommendations for brands and models:
Poke around on some of those links, and keep coming back with more questions. There are a lot of great tyers here that can help get you off to a good start.
