I went ahead and did your precessed Solar Returns for both years, which uses the sidereal zodiac. It takes precession into account.
For the one in 2012, Venus, Moon, Pluto, and Uranus will exert the strongest influence. Angular Uranus and/or Pluto in a precessed return chart is a strong indicator of change for that time period. Uranus is square Pluto in the sky right now, and the aspect will go exact twice over the next Solar Year. They will be squaring your nodes this coming year, so this collective transit may become personal for you. The SR Moon is conjunct Pluto and square Uranus, so this brings more energy to that square. This may indicate changes in domestic surroundings. You have SR Moon sextile your natal Jupiter in your natal 1st House and trine your Sun for this year.
Venus, ruler of relationships, is also angular and is semisquare the Sun. So, Venus-related themes such as will be important for the year. It is square your natal Saturn in the 1st House.
2013 is similar to 2012. The Uranus/Pluto square is angular, so more big changes. Venus is also angular that year and is highly aspected. Venus will be square Jupiter & Pluto and opposite Uranus. Additionally, Venus will be conjunct your natal Ascendant, and Jupiter will be tightly conjunct your natal Midheaven.
Checking your current periods according to your Vedic chart, you're running the main period of Venus and sub-period of Rahu (North Node). You have Rahu in your 10th House, which is house of career. It has a double aspect from both Jupiter and Saturn. Venus rules your 9th House and is placed in the 11th House. So, your current periods seem to show some support for career, relationship, and long-distance travel.
In your Vedic chart, Venus is pretty strong, has 7 points in its own placement, and has 13.4 points in V.Bala (Dasa). According to these and based on Venus' house rulerships and placement, Venus will give good results throughout its period.
Jupiter is currently transiting your 9th House of foreign travel. Jupiter scores 7 points in that sign, so it should give great results. For 2013, Jupiter will transit your 10th House of career and be in trine to its own placement. It will conjunct your sub-period ruler Rahu. Jupiter, however, scores 3 points in that sign, so the benefits from that transit will only be marginal. Jupiter rules your 7th house of relationships and marriage. On 2/26/2014, you will begin your Jupiter sub-period.
Overall, both years show big change. With angular Venus in both precessed Solar Returns and Moon trine Sun for 2012, relationships will be a major theme. In 2013's chart, angular Jupiter conjunct natal Midheaven may provide some support for career. It could involve foreign travel. Your current and upcoming planetary periods seem to be supporting these as well.
