Seeking Guidance on Embracing Islam Properly

Assalamu alaikum, everyone. I grew up in a household that follows other beliefs, right here in the Gulf region. Since my school days, I've felt drawn to Islam, and Alhamdulillah, I've tried to live by its teachings as best as I can-avoiding haram actions like zina, keeping my gaze lowered, and staying away from smoking or drugs. I've even been fasting during Ramadan quietly for years and praying five times daily, though I know my prayer might not be perfect yet. My family respects others' faiths but thinks one should stick to what they're born into. Now that I'm independent, I really want to do this the right way. I've read Quran translations and watched videos online, but I need proper guidance. Could you help with a few things? - Is it okay to just approach an imam at a mosque for advice? - Any tips or reliable resources to learn the basics before going, so I'm not completely lost? I want to avoid mistakes since I've been trying on my own. - What's appropriate to wear to the mosque? People here often wear thobes; can I wear one even though I'm not Arab or officially Muslim yet? - Which scholars or imams would you recommend for accurate, trustworthy guidance to fix any errors from the past? Jazakum Allah khairan for any advice you can share.
