I am assuming that they have not also devised some kind of matter manipulation technology. I'm also assuming that the plan is not to merely establish a colony that will almost instantly devolve into neolithic ignorance, that they'll want to continue, more or less, with modern technology & lifestyle:
They'll basically have to haul a large amount of raw materials and semi-fabricated components as well. They'll have to haul a large amount of redundant tools. They'll need to haul loads of basic hardware.
They'll need to haul many hand and simple power tools, in multiples.
They'll need to haul a staggering amount of food and water, for the journey there as well as for use until local sources can be determined safe. They will, at the very least, need also to haul water purificators. They'll need weapons to hunt, to defend themselves from predatory species, perhaps even to fend off aggressive locals.
They'll need to haul all kinds of medications, and chemicals as well.
The reason being: even though the planet you propose is "earthlike" it simply isn't Earth. They might be able to eat the local lettuce, but they'll have to have spades and watering cans and rakes and pruning shears and so forth to dig a garden. They might also want a tractor to plough the virgin soil. They'll need tools and raw materials like nails and screws to raise a barn. They can use local stone and timber for the basic structure.
They'll have to build housing, so will need carpentry and masonry tools, electrical equipment and wiring will have to be brought from Earth. If they expect to enjoy indoor plumbing, they'll have to bring toilets and sinks and pipes from home as well. And machines to dig pipe trenches. And build waste management systems.
Basically, the answer boils down to: look around your town and identify all the shops and warehouses there, from hardware to drygoods to electronics 7 appliances. Everything you and your neighbours will ever need to build, maintain, expand and replace any worn or broken part anywhere in your community will have to be brought from Earth by these colonists.
Future shipments from Earth may or may not be forthcoming. Budget cuts, wars, natural disasters, ships lost in space, all those things are real possibilities and would hurt your colonists. Communications may never reach home and people back on Earth will simply assume the colonists all perished. A second mission will undoubtedly be delayed or maybe cancelled.
In the meantime, your colonists are going to want to live a relatively modern and sanitary lifestyle until regular communications & shipping becomes a thing.
