I would like to also add some of my advices, even though I'm still early lvl researcher:
1. Regarding conference publication and journal publication I recommend conference that offer both, i.e. propose the conference paper to the indexed journal - somehow to kill two birds with one stone.
2. Work on the quality of the research and papers, as quality comes from the quantity (I followed such advice), but follow have a publishing strategy that depends on the field and possible journals and apply No.3 of Suzie's advices
Recently I have published an article entitled "Effective Strategies for Increasing Citation Frequency" which is available online on http://ssrn.com/abstract=2344585 . You can find over 33 different ways for increasing the citations impact.
I did a quick review to the useful techniques to boost your citations. I classify them as before, during, and after submission.
First: Before submitting
a. Before writing
1. Write high impact paper (Creative; Across disciplines; Hot topic; )
2. Publish with international authors.
3. Team-authored articles get cited more.
b.While writing
4. Cite your relevant past works (preferably at the first two sentences).
5. Make title short.
6. Carefully choose your keywords (indexed better) and use them in your title and abstract.
7. Use a consistent form of your name on all your papers.
8. Publish your article in one of the journals everyone in your discipline read.
Second: When submitting
9. Publish in journal with high impact factor.
10. Make your paper easily accessible (consider good open-access journal.)
Third: After submitting
a. Before Acceptance
11. Post your pre- or post-publication prints. Find publisher’s copyright and self-archiving policies.
b. After Acceptance
12. Ask for e-print from the journal or green open access.
13. Buy open-access right if possible.
14. Promote your work to well known researchers in the area.
15. Use social media. Make sure there are as many links as possible to your article, e.g. from your institute's website, Wikipedia, LinkedIn (used by 65 percent of the researchers)
16. Elsevier's Scopus is the world's largest abstract and citation database of peer-reviewed literature. Keep it up-to-date so others can find your article.
17. Keep your professional web pages (personal & university) and published lists up to date and keyword your article.
