Lots of good advice, so far. Let me add a few more.
1) Start way more seeds than you will think that you need. We all buy seed packages and then don't use all of the seeds, only to find them next year or years down the road when the germination rate is much lower.
2) Use cardboard.

It is free, it is non toxic and it works. I KNOW that I have been writing about using cardboard this year a LOT, like it is an end all, fix everything tool. Where I live there are tons of weed seeds lucking under the soil, waiting to pop up and take away my summertime to weeding my vegetable beds. I can guarantee that cardboard will work for tamping down weeds bc last year I piled ONLY soiled bedding from my horses stalls, up to 3 ft deep and
that alone kept most of the weeds down, and we talking about burdock weeds, mostly, which are my current bain. I have collected much more cardboard than you imagine from boxes that held office tables and chairs, and from pizza boxes AND Christmas...and other places. This winter I have been cutting and placing the cardboard under my fence lines. I rip/cut open the cardboard, put bricks on it to keep the winds from blowing it away and then dump from my stalls, removing the bricks, of course. If any burdock makes it through my "berlin walls of cardboard" they will have weed killer waiting for them this Spring. There are a great many weeds that survive decades buried. This is why many people don't till anymore, but I still do for a variety of reasons. Newspaper works, too, but you have to layer it.
3) Kill weeds with mulch. If you can cut ANY vegetation that hasn't gone to seed yet (with a mulching bag mower) you can put that down into between your plants. I did that (again) with a patch of burdock. I put it 3-4 inches deep. NOTHING grew up from underneath, and in less than 3 months it had literally turned itself into dirt. You KNOW that it is really good to grow in this year, too, bc mulch is full of microscopic bugs that create a lush environment for plant growth.
4) PREEN
PREEN PREEN PREEN PREEN PREEN PREEN PREEN PREEN PREEN PREEN PREEN PREEN PREEN
This is a granular pre-emergent that kills anything under 3 inches tall. I sprinkle it right around the stem of my transplants. You re apply 3 months later and nothing will grow next to your vegetables. FURTHER, old PREEN still works. I don't throw things away and my package of PREEN was easily 4yo Last year.
You need:
(1) gloves, gloves, gloves
You will lose them, so have extras. We won't judge if you take them Off sometimes, but
some gardening jobs will rip up your hands.
(2) hand rake
(3) hori hori gardening knife

You can measure, dig and plant bulbs with it and it is an instant small saw.
(4) spade or shovel
(5) wheelbarrow, buy cheap
I have 3 of these, and they double for me in the barn for my horses and chickens. I would suggest a small one for gardening, if you can only afford one, and then purchase a larger one later to unload stuff from your car. SAVE YOUR BACK AND USE A TOOL!!!
If you find an old one at a yard sale, you can use spray paint on all of the metal surfaces. I did that with my MIL's now 50yo small wheelbarrow. I LOVE that it has a solid, rubber wheel that never needs to be inflated.
(6) large rake
This helps especially during Fall cleanup.
(7) small folding knife.
I prefer the one that has a razor blade for the knife bc they are dirt cheap. I keep several in my barn and you can cut open bags with them and cut any material that you use to tie up plants.
Everybody here will rave over their favorite tool(s). Just start and you will have your own favorites.
