A good starting point for pronunciation is
vowels and mouth position. Look for a good explanation of consonants as well. Ones to look out for are 'wa' and 'fu' (nothing like the English equivalents). One that can seriously affect your intelligibility is ん(n) so give that special attention.
Mora and pitch are also very important. Mora helps you speak with the correct rhythm. For example, the word sensei should be spaced out equally into 4 mora, and not condensed into two syllables. Pitch accent often gets overlooked (including by myself), and you will seriously regret it if you don't give this attention from the start. These are the seven patterns, and you'll find one of the seven numbers in all
goo definitions after ◆アクセント :(
sanseido is an alternative).
0 low-high (no pitch)
1 high-low (initial high pitch)
2 low-high-low
3 low-high-high-low
4 low-high-high-high-low
5 low-high-high-high-high-low
6 low-high-high-high-high-high-low
Shadowing is also a good way to develop general pronunciation and intonation, while remembering chunks of language too.
Other than that, getting a native speaker to correct you will help a lot. They may or may not be elusive where you live, but you can find plenty of them here
