Hey guys I have Technic and Tekkit and stuff and how the forget do I do this hgsdf.
What I would recommend is building a house like you normally would, but try to build it near a Millenaire village so you can trade with them and don't get lonely. If there are mountains near the village then try to make your home in them so the mondays don't fill your home in while they're building something. It would also be optimal to have an oil geyser in viewing distance but that isn't very important, it will just help out with the fueling of your machines later on.
So after you've settled down, the best way to mine would be a 16x16 quarry so you can get a ton of stone as well as a forgetton of ores used by the mods in whatever pack you're using. Unfortunately you're only going to be using the BuildCraft and IndustrialCraft stuff after you've gotten a large quantity of resources, so after you've hollowed out a shaft to bedrock you can get to work on making intricate machines, factories, farms, etc.
I really wish there was a way to take advantage of BuildCraft's machinery near the beginning of the game. Building machines to mine and craft stuff for you around the endgame kind of defeats the purpose for me. Regardless, the Technic Pack adds a lot of cool content.
