Hi,
Please check what exactly has been done previously, during the Navagraha Homa/Havan. If Rahu Shanti Homa/Havan have been done. If done, I’m inclined to think there would be no need of doing so all over again.
Technically upcoming Pratyantara Dasha of Lagna Lord Venus/Shukra starting soon should give a bit of a breather. So, please do not stop going all out on making sincere and focused attempts at suitable/open positions (either internally or outside).
That said, please be informed Ketu placed in the 10th house of Karma-Sthana and posited in the Lunar Constellation of Ketu will continue to be active. So, it would make sense for you to consider offering special prayers on a daily basis to Lord Ganesha, with unwavering faith, bhakti/devotion and a strong Sankalpa.
Take care…
