Masha Allah, may Allah accept your umrah...
I would suggest to pray from your own language (if you cannot pronounce and understand the Arabic correctly) especially during TAWAF AND SAIE. Allah understands all languages. Also, be careful and mindful of your actions inside the Haraam - avoid those innovations being done by other worshipers. These are some tips:
1) Start from Black stone raising your right hand and say 'BISMILLAHI ALLAHU AKBAR' WALILLAHIL HAMD then start praying (any prayers as you wish, but don't forget to ask for forgiveness for yourself, parents, relatives and the whole Muslims) from your own language (this is advisable for those who cannot understand Arabic and cannot pronounce it correctly).
2) Do not raise your voice while you are praying in order not to distract the concentration of the other pilgrims.
3) When you reach to the Ruknul Yamani (rub it with your hand, but don't kiss your it or your hand). If you're not able to touch it just proceed to the Black stone without raising your hand (at the RUKNUL YAMANI)..
4) In between RUKNUL YAMANI AND BLACK STONE, say the following DU'A 'RABBANA AATINA FEDDONYA HASANAH WAFEL AAKHERATI HASSANAH WAKINA 'ADHAABANNAR' THEN
5) Kiss the Black stone if you can, if not just raise your hand towards it and say ALLAHU AKBAR then proceed again and pray (du'a).
6) process until you finish 7x
7) After completing 7x, find a place behind Maqamu Ibrahim and Pray 2 Rak'ahs of Sunnah, reading Fatiha and Kaferoon on 1st Rak'ah then Fatiha again and Ikhlas on the 2nd rak'ah.
8) Then proceed to drink Zamzam water (drink as much as you want) then
9) Try to find a way to go to the MULTAZIM (this is between the Black stone and the gate of the Kaabah) and make du'a (pray) - prayers here are being accepted by Allah and this is done by the Prophet SAW.
10) After which, proceed to the Mount of Safa by saying "INNAS-SAFA WAL-MARWATA MIN SHA'A ERILLAH', when you reach to the top of the mount Safa say 'ALLAHU AKBAR 3X' LAA ILAAHA ILLALLAHO WAHDAHO LAA SHARIKALA LAHUL MULK WALHUL HAMD WA HOWA 'ALA KULLI SHAIN-QADEER, LAA ILAAHA ILLAHO WAHDA WA NASARA 'ABDA WA ANZAZUNDAH WA HAZAMAL AHZABA WAHDA - THEN make Du'a (anything)...descend towards mount Marwah, upon reaching mount warwah (note: you have now completed 1), repeat what you did in mount Safa. then Go back to Mount Safa for the 2nd lap, then return to Marwa for 3rd lap - continue until you have complete 7 lap. NOTE: YOU SHOULD COMPLETE YOUR SAI AT MOUNT MARWAH....NOTE: ENSURE TO JOG IN BETWEEN THE GREEN LIGHTS...
11) After completing 7 laps, go to the barber and shave your head...this advisable for those first timer...it gains more reward than just trimming your hair...and ALLAH KNOWS BEST....may ALLAH ACCEPT YOUR UMRAH AND MAKE IT EASIER FOR YOU....
